[rallye bob]

Aubrey;
I think you should try Amsoil, Dominator 10W-30 Racing Oil..... In your fine ride....

Brad Penn or Valvoline VR1 racing oils.Very good oils,for older cars

Everyone will recommend what they use and/or what their engine builder recommends and sells.

Further, what was the must run oil last year according to those that post on these forums isn't today, the recommendations change with the wind and who spends more $ on their marketing campain.

Me, I've been using Mobil 1 5W-30 since 1986 in my passenger cars and since 1991 in my race engines and I ain't changing because I read on a forum that some other oil is better.

Your only choice is deciding what viscosity to run as well whether you want to run conventional, semi synthetic or full synthetic. Otherwise for what you have and are doing oil is oil.

If you feel you need zinc, Lucas and others sell additives.

Thanks guys...
yes, I guess it's the synthetic vs mineral again.
Is there an advantage to synthetic ?
I never found one.
I guess what !'m after is stability. I never have to worry about going rounds, and being unable to cool the engine down. PLENTY of time there ! So, typically, I CAN keep the engine cool for the pass. This is why I'm leaning towards a thinner viscosity... say a 10 / 30 or even 0 / 30 synthetic. However, this engine cost me a freaking FORTUNE, and I'm probably more concerned about it's survival, than that extra 4 HP !
So, I'd like my oil pressure to be kept around 65 for a run... but have enough stability to stay there, should I be in that environment where the temperature is allowed to get up there.
People tell me that only synthetic can do this ?

I would recommend Amsoil synthetics as well. They have a wide variety of viscosities to fit your needs and all have high levels of zinc. Personally, I use the 5w20 Dominator. My engines exhibit excellent wear characteristics. Different viscosities will affect the average overall oil pressure.

Feel free to PM me for sources and more info.

Joe Gibbs 5w-30 synthetic has worked for years while still having decent oil pressure. And the engines come apart looking really good.

[1320racer]

if the engine clearances were set correctly and it had proper lubrication there's no reason the engine shouldn't "come apart looking really good".

Joe Gibbs oil is just the latest player in the game the internet crowd is talking up, before it, Brad Penn was the flavor of the day and before it Royal Purple.

All I know is that I've been using Mobil 1 for 26 years without issue despite the changing formulas and EPA mandates and my engines always come apart looking good and my last freshen up was after 500 passes seeing 8000 in the lights every weekend, 36 weekends a season.

Good luck finding a stock/super stock racer that puts half as many passes on his engine before freshening.

Joe, what part of the truth and the facts below don't you understand or agree with? Enlighten us

No where I have advised the op to run Mobil 1 because I run it.

[buzzinhalfdozen]

No where in either of those posts did you offer anything more than YOUR opinion, you bad mouthed a few oil brands of which you've probably never ran, you stated you've ran Mobil1 for26 years though your engine has nothing in commom with the OP's. You completely failed to answer my question of what class "E" is, you've expressed YOUR truth, offered no facts so once again you've offered information irrelevent to the thread. IF you respond please include your S/S class and how far under the index your perfectly scienced out "S/S legal" unit runs as I've looked again and fail to see the "E" designation. FWIW it's OK to be a bracket racer, we all are to a point but at least have the stones to fess up to it, and quit giving bracket racer advice to racers who are trying to make their stuff FAST!

[1320racer]

I haven't bad mouthed any oil, I've offered my opinion as did everyone that replied has while also offering first hand experience with the oil I have been using for the past 26 years! Lastly, you assume too much. I have run Royal Purple and I run Joe Gibbs XP-1 in my son's jr. dragster.

The op will and should run whatever type and viscosity oil HE chooses regardless of what my or anyone else's opinion is. IF there's anyone's opinion he should be listening to, it's his engine builder!!!

Joe, get over yourself and your what does a bracket racer know mentality.

THIS bracket racer KNOWS!

That said, I'm sorry that my car is over a second quicker than yours, I'm sorry that I race more weekends in a season than you, I'm sorry that I race for more $ than you, I'm sorry that I win more than you, I'm sorry that I don't run the same oil you do, I'm sorry that I don't feel having to buy a new window net every 2 years is a big deal and I'm sorry I don't race in any Super Stock class.
