Hey all, I have trouble with the Search option at times and cannot find what I am looking for. So please, don't shoot me if these questions have been asked :)

1) If I wanted to start using premium fuel, then the best way would be to drain my tank till the Low Fuel light comes on, and then fill 'er up?

2) If I start using premium fuel, would there be any issues if I stopped and downgraded?

3) Has anyone used Q Power, and what are your comments on it? is there anything that is comparable/better?

4) I will be having to replace my front two tires soon. My back ones are great looking tread-wise, but the fronts are kinda low. I currently have Goodyear Eagle LS 225/50R16 91S all around. I would prefer to keep all the same brand/type and am looking into used tires (unless I find that new would be better), but am running into the trouble of funding for them (farking expensive tires). Is there any tires that any of you would suggest to put on my car, with the Goodyear's most likely going up front (for the balance/rotate)? I'll also be getting a semi-needed alignment afterwards :)

5) I also have an issue with a slightly higher than normal idle when I first start my car for the day. It will stay at 1k, then drop slowly down to the normal 650 after several minutes of running (I try to let it run in the driveway before I leave to avoid complications). Is this semi-normal or what could be causing this?


I put all of these here, in his general Tech section for the sake of consolidating space. Please answer kindly and post links if you have found things that I haven't. I get sick of Searching sometimes, cause as I said before I can't always find what I need :)

Thanks in advance

DON'T run your gas tank to the bottom !

Some people here found out fast (the hard way) that our fuel pumps do not like it.
The fuel pump requires gasoline to keep it cool.
They are expensive $$$ to replace.

Just start filling up with premuim next time & every time after that.
Eventually, your gas tank will have all premuim in it.

No problems down-grading afterwards; unless you have a modified PCM.

IMO, would not recommend going below 89-octane gasoline; because of the ethanol blending that most places are now using.

...4) I will be having to replace my front two tires soon. My back ones are great looking tread-wise, but the fronts are kinda low. I currently have Goodyear Eagle LS 225/50R16 91S all around.

Trust me...
Get focking all new 4 tires !

Your stock Goodyear Eagle LS tires are now over 8-years old.
It doesn't matter that your tires still have treads left.
The rubber is now old & not as sticky.
& are cracking.
All major tire manfacturers now recommend changing tires after 6-years old.

I changed my stock GY Eagle LS tires at 5-years with 5/32" tread left.
But spider like cracking was also starting to showing up.

I am also thinking of changing out my Bridgestone Blizzak LM-22 winter performance tires this season; that are going on their 6th winter season with 6-7/32" tread left.
But they don't seem as sticky anymore.
& + I am loving/jealous of my Mom's Nokian Hakkapeliitta RSi winter tires (that I bought her last winter) lol

& why is your tires not wearing out evenly ?

...5) I also have an issue with a slightly higher than normal idle when I first start my car for the day. It will stay at 1k, then drop slowly down to the normal 650 after several minutes of running (I try to let it run in the driveway before I leave to avoid complications).

Normal.

Goodyear Assurance TripleTred tires (http://www.tirerack.com/tires/tires.jsp?tireMake=Goodyear&tireModel=Assurance+TripleTred&partnum=25HR6ATT&vehicleSearch=false&fromCompare1=yes&place=6)

Are really good, if you want a all-season tire; that is technically not a "performance" rated tire.

lol, Goooooo Mike Jung!

Thanks Sik, for 5 I wasn't sure because it did that before, but it would top out at 800, then now starts up at 1k. But I figured everything was fine :)

I never run tanks down to Empty anyways, and try to stay over 1/2 at the least (usually fill up every 3/4 tank lol), I know going below 1/2 tank wastes more gas anyways.
With the tires, they are not the stock ones :) The guy I bought the car from has replaced all four at least once (I have the recipt and he got a HELL of a deal, $90 per LS!!!), and I don't know why they aren't wearing out evenly. I suppose it -might- have to do with the fact of when I first bought it, I tended to be heavy on the pedal and he may have been as well. I know that will run your fronts down faster (did that with my first car, hehe).

Mike - I agree, I have been extremely satisfied with my GY Assurance Triple Tred's. Switched to them after the stock's came off on my 01 GAGT. Well, technically my 2nd set of stocks, since the dealer gave me 4 new ones right at 36K because I complained about the infamous tire noise issue. Of course, the idiots at GM only allow them to change the front 2. You then have to go home, rotate them, come back and tell them the noise came back after you did a rotation. LOL
What a waste of freaking time.

Yeah, I like those tires, my buddy at Belle Tire suggested them. I wanted those, and then realized they don't offer them in 18s. But then again, I've pretty much quashed my ideas for getting 18s on my GA, just won't have the money and by the time I do, I will probably get another car :(

Anyways, what about if I just wanted to get two tires for now to replace my current front ones? Would the x3Tred be fine for the rear (cause of the rotation) with the LS' up front? or just leave the LS' in the back, switch them, and put x3Tred up front?

Quaker State synthetic motor oil :thumbsdow

Pennzoil motor oil = :thumbs:
Especially, their new Pennzoil Platinum (EOP based) synthetic motor oil.

* reference source from Bobistheoilguy.com forums (http://theoildrop.server101.com/cgi/ultimatebb.cgi): from a guy that works at/for Pennzoil (which owns Quaker State; & Pennzoil is owned by Shell)
(Pennzoil motor oil always uses better stuff, than Quaker State motor oils.)



I myself use Castrol Syntec 0W-30 (PAO based with esters blended) synthetic motor that is made in Germany.



PS: Oh, & there is always the Mobil 1 EP (PAO based) synthetic motor oils.
If money $$$ is no object: Red Line (Ester based) synthetic motor oils = over-kill for a NA GA though lol

You really want to open a can of worms, don't you ?

from: Walmart Rant (http://www.grandamgt.com/forum/showthread.php?p=541679#post541679)


You should only have:
4- snow tires on the car (not a mix of snow up front & all-season on back) &
4- same model of tires on the car;
whether or not same size is debatable, as small tires have less traction than larger tires of the same model.


See what Michelin says & Watch the video from Michelin (http://www.michelinman.com/care/tip6.html#5)
Having less traction tires in the rear could case the rear to spin out.

Don't even think about putting "directional" tires in the mix; with your 2 old ones.

Example: You put the new directional tires in the rear; & you won't be able to easily to rotate them without unmounting them from the rim.

IMO:
Get 4 new tires like the Goodyear Goodyear Assurance TripleTred's.
or
Get 2 new Goodyear Eagle LS tires & put them on the rear.


But before doing that:
Get you front end suspension fixed & aligned !

You can't compare them.
It is like Apple & Oranges; a different category.
...Are really good, if you want a all-season tire; that is technically not a "performance" rated tire.
Not a Goodyear Eagle model.
Not that they have many good performance tires IMO.

& IMO I would not run BFGoodrich g-Force T/A KDWS (http://www.tirerack.com/tires/tires.jsp?tireMake=BFGoodrich&tireModel=g-Force+T%2FA+KDWS&partnum=25WR6GFTAKDWS&vehicleSearch=false&fromCompare1=yes&place=4) all-season tires.


Here are some suggestions below:

http://www.tirerack.com/images/tires/bridgestone/bs_potz_re960as_pole_ci2_l.jpg
Bridgestone Potenza RE960AS tires (http://www.tirerack.com/tires/tires.jsp?tireMake=Bridgestone&tireModel=Potenza+RE960AS+Pole+Position&partnum=25WR6RE960PP&vehicleSearch=false&fromCompare1=yes&place=7) :wow: (Which replaces the RE950's, which I currently have.)


http://www.tirerack.com/images/tires/pirelli/pi_p_zero_nero_ms_ci2_l.jpg
Pirelli PZero Nero M&S tires (http://www.tirerack.com/tires/tires.jsp?tireMake=Pirelli&tireModel=PZero+Nero+M%26S&partnum=25WR60NMS&vehicleSearch=false&fromCompare1=yes&place=1)


http://www.tirerack.com/images/tires/michelin/mi_pilot_sport_as_ci2_l.jpg
Michelin Pilot Sport A/S tires (http://www.tirerack.com/tires/tires.jsp?tireMake=Michelin&tireModel=Pilot+Sport+A%2FS&partnum=25YR6SPORTAS&vehicleSearch=false&fromCompare1=yes&place=2)


& Of course you take them off, when it gets below 5°C/41°F (for the winter); even though these are "all-season" rated, which really means 'nothing' IMO (in terms of winter driving performance). (If you want more details PM me, & I'll make a new thread about all-season tires.)
& get your winter rubber on ;)
For maximum traction in the winter time (yes, I am a ;psycho :D lol)

First off, a little update. After reading on the premium fuels and such, I decided to just go with 89 midgrade. It seemed a better solution, as many times I read that 93 grade is overdoing it, and 89 was a nice inbetweener.

Anyways, here's my thoughts
1) I can't find any threads on motor oil that discuss the different weights and such. I would like to know what a good weight for my GA (stock, except for GM High Performance plugs/wires and K&N drop-in filter) would be. I would be looking for something that the best bang (not literally lol) for my buck.

2) As for tires, unfortunately I do not have the money to buy two sets of for. You must remember, I'm technically poor :( Heck, I would like to get a couple used Eagle LS' to replace my current two (done it before with another car) so that the tread will be close to what's on the back right now. However, if I find out that new would be the best to do for my two tires, I will do so

3) As for the suspension, are you referring to my strut mount problem? That's in the rear and I plan to get it fixed in a few weeks via the aid of a friend and the proper tools :) As for the alignment, I was under the impression that it should be done after getting new tires, to make sure everything is correctly positioned, but I could be wrong.

Also, I was kind of surprised about the Pirelli PZero Nero M&S being on $99, I thought all Pirelli's were expensive lol As for the Bridgestone, looks nice but I think I'd rather go with Michelin or Pirelli (for that price hehe). I hate being on a limited budget, and not having much to spend to cover needed repairs on my car ><

I think that's it for now, I know I'll remember more later so lol

Have the alignment checked first. If nothing is out of spec then an alignment should not be needed. Any competent place doing the alignment would do this anyway.

On a stock GA you really don't need anything other than 87 Octane, even with the 10% ethanol blend. (Sorry Mike)

99GTCoupe
09-18-2006, 03:57 PM
Well I can tell a nice difference in how my car runs (almost 8 gal of 89) with the midgrade in. I'm just gonna stick with it, cause there's no real point in premium unless I go and get a new PCM. It starts better and runs smoother than it did :)

Mike Jung
09-18-2006, 05:30 PM
IMO:

About 87 vs. 89 Octane Gasoline ? (http://www.grandamgt.com/forum/showthread.php?t=10606)

PS: What happens to GAGT's in the summer time heat (& are load up with weight, like for a road trip) when running on the highway with traffic ?
Knock retard starts to happen.
So sometimes 'Premium' does do alittle better, as there are 2-fuel tables for our GA's.
But the controversy will go on forever; but I trust some of the guys here that scanned their GA's for knock retard, when running 87-octane in the summer heat.

...1) I can't find any threads on motor oil that discuss the different weights and such. I would like to know what a good weight for my GA (stock, except for GM High Performance plugs/wires and K&N drop-in filter) would be. I would be looking for something that the best bang (not literally lol) for my buck...
xW-30 grade is recommended for the GA; specifically 5W-30.
But it depends on the specific oil.

Like I would not run just any 0W-30 motor oil in my GA; as some are made for only extreme cold/winter use only.

& in some cases: for the summer 10W-30 is better than 5W-30.
But in most cases 5W-30 has better technology behind it; & is better than 10W-30 in the summer.

In the winter: 5W-30 (or 0W-30); but some 0W-xx are not really much better than 5W-30 until it is below -30°C/-22°F. (Like German Castrol Syntec 0W-30 & Mobil 1 0W-40; which both are European spec oils.)


Best bang for the buck depends on what is important to you & how you do your oil change interval.

Like some will do short oil change intervals with like a "cheap" (but good) dino oil like Havoline 5W-30 that I heard is cheap in price in the US but does good in the handling wear in the engine (but I don't really follow dino oils that much).

To people changing their oil once per year or if the oil change light comes on:
with premuim synthetic motor oil like: Germany Castrol Syntec 0W-30, Amsoil (not counting the XL-line), Mobil 1 EP, etc...

99GTCoupe
09-18-2006, 06:31 PM
Well I always do 3k oil changes, and just want a good all around oil to use. Basically would it be worth it to start using Synthetic oil? Also, I'm due for a change atm, but can't get it done until Wed, since I am taking it to a dealership 'close' by cause they will do a full service, plus a free wash for $26.99 lol

Yeah, it's a lot, but I can't get my oil done myself yet. I wanted to do one last good oil change before I start (plus cause I have to get it done ASAP, I want to find a good oil to use myself).

Stepping back to the gas part real quick. I don't have any numbers on hand but I believe that BP tends to be best in terms of cleanliness of fuels. I also know that Shell and I think BP (as well as others) have recently comitted to having their fuels within the stricter guidelines suggested for ideal purposes from the Big American 3. Basically they've been making cleaner fuels with more detergents to help prevent issues with injectors.

I really don't want to have to worry about my bulb falling out and want a replacement, but it's not listed here (or on the following page) (http://www.grandamgt.com/part_numbers/page1.jpg). I posted in that forum to get the part number, but if it's gonna be expensive, I'll be pissed. Anyways, I'm gonna post and see if anyone has one they wanna sell :D

That would be normal for any car to run like that. When you first start your car the engine is cold so it will idle high until the car runs for a bit then it will drop down.

99GTCoupe
09-25-2006, 03:36 PM
Yeah, I had been just a little worried that it was up at 1k RPM; but since it ran fine I figured everything was okay. I just try and let it idle until the RPMs drop back to 650.

I have another question (not GA related). My gf has an 01 Saturn SC1 and it has started idling high and sounding horrible (until it warms up, of course). However, remember that during the winter the car never did this (and hever has at all), and it started out of nowhere about a month or two ago. We have replaced the plugs (they really needed it anyways :D), but didn't help. Any ideas what could be causing this? Oh, it sounds like the fan is stuck on jet-engine-turbine-mode ><

I tend to wait until the idle drops to like 1K (or below); in the winter time.

I've read some threads on Seafoam already, but haven't found my simple answer yet :)

I just used Seafoam last week in my gas tank, just to help things. Filled up, poured in, yadda yadda. My question is: Should I add it to my oil at all? I have 2k miles before I'm due, or I could do it now. Also, I'm not quite sure about adding it to the engine in the other ways, though I haven't Searched on that yet. I'll take a look later on that, though, and see what I can find around here. I just want to know if adding to the oil (now or 2k later) would be good in combination with the gas tank.

SikMindz

You'd want to add it to your oil only if you plan to get an oil change within I'd say 500 miles after. Being a solvent you wouldn't want everything the Seafoamed cleaned out to be floating around your system that long.
