OIL??? What is best??? hey guys...i have always used castrol syntech...i have recently heard that it is not really synthetic or it is not good something like that...i plan on using the mobil 1 synthetic that is for race engines 15 w 50 ....what do you guys use??? i know the royal purple is really good but no close place to get it here...what filter are you guys using also? and i have a friend that uses RISLONE in his car everytime he changes oil...he has 130K on his 97 z28 and it is still running strong...he swears by the rislone stuff what do you guys think?

Re: OIL??? What is best??? Oh jesus.. another oil debate. Well, im not much for oil tech and stuff, but i use Royal Purple 15w40 with the K&N oil filter (the longer one).. Works out good for me.. dunno what everyone else runs. But in opinion 15w50 is too thick.. i think 15w40 is the thickest you can go...

Re: OIL??? What is best??? Just because I know I can trust it and get it anywhere I went with the Mobil 1 5w-30 and Mobil 1 filter, whatever that supersyn stuff is they say it protects wear on the engine a whole bunch. I guess we'll see about that after I use it a while

Re: OIL??? What is best??? Stay away from 15W50, its' way too thick for a LS1 motor. Instead, run 5W30 or 10W30.
For normal street duty and a few drag strip runs, I use a stock GM oil filter.
For oil, I use Amsoil 5W30. Never had any oil related problems even using it in the drag race cars. Fossil oils are OK to break-in your motor. After that, run a quality synthetic. Amsoil, Royal Purple and Redline are good choices.
Hope this helps and enjoy your car.

Re: OIL??? What is best??? Stay away from 5w30 as it tends to thin out quicker and turn into 5w20, especially Mobil 1.
Also stay away from 15w50 and 20w50, they are too thick. 15w40 is ok.
After all the rumors about the new Mobil 1 not being as good, I saw the first oil analysis in someone's car with a comparison to the old Mobil 1. In this guy's car there was a significant reduction in wear metals with the new stuff! He was using 10w30 (which I prefer).
I'm interested in seeing more results, but so far I'm impressed! I was one of the ones that suspected the new stuff wasn't as good either, I'm glad I was wrong!
Here is a link to that analysis report:

Re: OIL??? What is best??? I'm also VERY impressed with the new Mobil One. I made the mistake of using a 5W-30 on my last oil change, but I have noticed my oil consumption rate has dropped SIGNIFICANTLY! Whereas I may have consumed 1.5 qts over a 3000-mile change interval with the old stuff, this new Mobil One has lasted throughout the entire 3000 miles without dropping below the "normal" hashes on the dipstick... and this is with 5W-30 oil in Texas heat! I'm going to stick with this for my next oil change and have an analysis made at the end of its life.

Re: OIL??? What is best??? You can easily go longer than 3000 miles on Mobil 1, I've gone up to 7k on it in my wife's car, and I know it will go further. Some people I know have done 15k oil changes with Mobil 1 for many years and have hundreds of thousands of reliable miles on their vehicles. Mobil 1 oil has a very high TBN (acid neutralization) so it can handle the long drains well. Changing it at 3k is not needed, the oil is still practically new at that point, and in a good engine there will be almost no contaminents in that oil at all (less than 0.5% fuel for example)

Re: OIL??? What is best??? Hehehe...It figures that a week after I spend $50 on 6qts of Redline, it comes out that the new Mobil 1 may not be so bad after all... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: OIL??? What is best??? I use Mobil 1 with a Mobil 1 filter. I did try Royal Purple and had no problems with it. The only oil Synthetic-wise I've heard stay away from, is Quaker State... <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

It is just that the new Mobil 1 is not as bad as many of us had thought it was. This seems to happen every time Mobil 1 reformulates. Next time they reformulate I'm gonna keep my mouth shut. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: OIL??? What is best??? Mobil 1 has never done me wrong, extra insurance for year round driving, and mostly stop and go also.Im interested if any body has tried lowering oil level in pan with good syn. to gain power at track? Should be able to drop 1 quart for drag race usage. Anyone?

Re: OIL??? What is best??? I see I'm not the only one who has thought of this! I was thinking of running one less quart of oil before going to the track, then making 3 runs like that, then putting the quart back in and making 3 more. I figure it might be worth a few horsepower due to less oil sloshing around. But at what cost I wonder? Would it increase engine wear? Once I switch to Schaeffers oil, and have a good coating of moly on all my engine parts, I may try it out then, that way I still have the moly for secondary protection.

In the glove box was a VHS tape version of the owner's manual. One section of this tape explained how to "set up" the car for racing...tire pressures, how to adjust the suspension, etc. On the tape they recommended ADDING an extra quart of oil when racing. Reason being..when your engine runs at high RPM's, the oil is pumped into the engine faster than it drains back to the pan, so the extra quart ensures that there is always plenty of oil in the pan.
IMO: removing a quart of oil would also cause the remaining oil to overheat more quickly.

Re: OIL??? What is best??? I agree with that, when road racing you definitely want to add more oil, that way you prevent oil starvation in fast corners.
But with drag racing, you don't subject the engine to duress for as long of a period of time, and often times you start out with the engine at slightly below operating temps too. So you'd definitely be safer doing this practice in a drag racing situation than you would if you did it in a road race situation.
