i use 5w-30. the manual recommends it and i'd think that 10w would be too thick. i'm not sure if i would ever trust 0w though.

 

yeah, those are stock m6 #s. i saw in the gm hi pro. mag a 98 or 99 a4 bone stock made 270ish rwhp. i can't see a car having an ls6 manifold upgrade putting down those numbers, but maybe he got a fluke from the factory... congrats!

 

why wouldnt you trust 0W?

 

Yeah I know the 02 SS and WS6 package came with the ls6 intake and some other minor things like no EGR, but that makes me feel a lot better knowing that other auto's stock are putting down 20 less to the wheels than me. Ya know I've heard the 02 ws6 is actually more around 375 crank hp. Cuz if you lose about 20% of your horsepower through the drivetrain it works out perfectily.... 302 whp.

 

too thin. i know a lot of people run it but i'm a little hesitant. it's like goldilocks and the 3 bears....10w = too thick, 0w=too thin, 5w = juuuuust right lol

 

totally wrong, 10W, 5W and 0W are all the SAME. the only thing the first number means is the cold start up protection. the lower the number, the better the protection. after the first 5 minutes of idling in cold weather and the first number is moot. 0W30, 5W30 and 10W30 are all the SAME weights.

 

actully, all LS1's produce about the same amout of power. obviously 01-04 with the LS6 intake will put down a little more, but not enough to shun a 97-00 LS1 engine.

 

Well I know all the LS1's are badass, you just get those "factory freaks" puttin down more than everybody else lol. I did race a std. TA a few weeks ago and all I could tell he had done was cat back and it was basically even. He was in front of me and punched so I do the same and I just BARELY started to creep up on him. But it was fun running another LS1.

 

just remember the driver plays a big part in races like that. he may have had a stick and didnt know howto drive that great

 

A4 making over 300 is always a great day!

 

great numbers man, i think my car was a factory frekar to, my friend got granatelli maf, lt's ory, borla catback, no cats, slp lid and mor on his 2002 and my car felt faster, but i spun a bearing, and now i am putting it to geather with H/C and more so i vill never know,

are the 02 car any faster,? the 98 cars got bigger cams, more lift/dur but less LSA,

i felt like my 98 car had more mid range power and low end, but my friends 02 more peak

 

Were the numbers SAE corrected? That makes a difference...

I run M1 0w40, about the same consistancy as GC 0w30.

 

Just be safe keep using the 10w-30 mobile 1 synthetic that's what I use. I used royal purple same wait for a couple of oil changes and it runs a lower pressure so I switched back! But Royal purple in my m6 and differential.

 

ummm no. the weight of a motor oil has to do with its viscosity (aka thickness). while it's true that the biggest difference you'll experience is within the first few minutes after startup, the thickness of the oil isnt gonna suddenly change after driving for an hour. also, anyone living where it can gets cold (below freezing and ESPECIALLY below 0) should run a lighter weight oil. do some research first before you comment on other people's posts with misinformation.

really, hmm i didnt know they were still making fbodys in 03 and 04? and 97 still used the lt1 engine, not ls1. again, do some research before making your posts. at least you knew they changed to the ls6 intake in 01, so the post wasn't a total bunch of misinformation.

 

Well actually he was driving an automatic cuz I heard it shift down and slowly into the next gear lol.

 

Yeah I remember reading that the 01's and 02's were fitted with the 5.3 cam to give it more bottom end power but I can tell it's more of a top end screamer than anything

 

your right it wont change after an hour of driving. it will change after about 10 minutes of driving. because the 1st number has NOTHING to do with the weight or viscosity. the 1st number is the cold start up protection. the first number is a base, that has polymers added to it to keep the oil from thining out as it warms up.
want proof?

"Multi viscosity oils work like this: Polymers are added to a light base (5W, 10W, 20W), which prevent the oil from thinning as much as it warms up. At cold temperatures the polymers are coiled up and allow the oil to flow as their low numbers indicate. As the oil warms up the polymers begin to unwind into long chains that prevent the oil from thinning as much as it normally would. The result is that at 100 degrees C the oil has thinned only as much as the higher viscosity number indicates. Another way of looking at multi-vis oils is to think of a 20W-50 as a 20 weight oil that will not thin more than a 50 weight would when hot.


Multi viscosity oils are one of the great improvements in oils, but they should be chosen wisely. Always use a multi grade with the narrowest span of viscosity that is appropriate for the temperatures you are going to encounter. In the winter base your decision on the lowest temperature you will encounter, in the summer, the highest temperature you expect. The polymers can shear and burn forming deposits that can cause ring sticking and other problems. 10W-40 and 5W-30 require a lot of polymers (synthetics excluded) to achieve that range. This has caused problems in diesel engines, but fewer polymers are better for all engines. The wide viscosity range oils, in general, are more prone to viscosity and thermal breakdown due to the high polymer content. It is the oil that lubricates, not the additives. Oils that can do their job with the fewest additives are the best."

mis information? misinformation right here ^^^^^. the F-body is not the only car they put the LS1 in. 97 was the first year for the LS1 in the Vette, then in 98 the F-body, then in 03 still the vette and 04 it was the GTO. you need to get your **** straight before you call me out on my "misinformation" you should start here

 

oh yeah,

Ripper415=

i was just trying to help you understand, but you turned into an arrogant little *****. so, sorry bout your luck.

 

What do they do to SAE correct it and what kind of difference does that make?

 

i apologize bww. i'm man enough to admit when im wrong. i had a bad day at work and i guess i took it out on you. i spent a fair amount of time on that site you linked and as the title suggested i did find out more than i ever wanted to know about motor oil. most of the sites online dont go into anywhere near that much detail about oils and only say stuff like this....

"Motor Oil weight and viscosity grade

Motor oil comes in many different weights and viscosity grades. The motor oil weight or viscosity grade, such as 10W-40, specifies the oil's thickness, or viscosity. Viscosity is basically a measurement of resistance to flow. The higher the number, the thicker the motor oil. Thicker more viscous oil tends to protect against wear better, but it can also steal horse power and gas mileage from your engine because it's harder to pump and has more drag on engine parts. Thin oil flows easier, which results in better gas mileage.

Overall, synthetic motor oil flows easier than conventional oil, which in turn provides better gas mileage. For example, 10W-40 synthetic motor oil flows much easier than 10W-40 conventional motor oil."

this level of understanding is what i (up until now) and most people out there have about oil. so when someone who is better informed such as yourself comes along and says something that completely contradicts what most people believe to be true (without providing more background info as you did in your last post), it comes across as total bs to people like me. however, that didnt justify my acting like an ***.

in defense of my last quote about the model years....yes i knew the ls1 was in other cars besides the fbodys but since this is an fbody message board it honestly didnt occur to me that you were referring to any other car. it's also not really fair to compare the power of different model cars even if they use the same engine because they'll have different numbers based on various other factors like exhaust setups, gears, etc. plus i was under the assumption you were a retard from the top half of your post so that probably skewed my thinking a bit lol.

once again, sorry dude. if i knew you in person i'd buy you a
