Recommended Engine Oil ?

[Aubrey N Bruneau]

I'm in the process of getting my old beater ready for Mission later this month. Need to change oil. Been using a zinc fortified 30W ( no longer available ), but I know I don't need that much viscosity in an engine thst doesn't see extended driving, or high temperatures. Even fully warmed up, oil presure at 1200-1300 RPM idle, is 25-30... and goes 70+ over 2500. With the engine cool... like tring to make a fast qualifying pass, my oil pressure at RPM, goes scary high... over 80.
Don't like that.

So, do you guys have a recomendation for oil brand / type, viscosity ?
I have an unusual oil pan on my car. It's actually an over-the-counter GM replacement pan, which has an extra 2 quart capacity ( I run 7 quarts in the 8 quart system ). So, I don't have to worry about running the pan dry.

Just trying to make a few good passes there at sea level !
Hey, bringing a spare rear end pumpkin too !

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.

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

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.

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!

[buzzinhalfdozen]

Aubrey, I appoligize for disrupting your post No disrespect was intended. As I stated please make conections with someone with a similar combo and see what they're running, I've got a Modified engine and it has no direct correlation to what you're running so my input would be mute. Again sorry for the rant in your thread. Joe

[1320racer]

As you should being that you only replied to this thread to attack me/my advice with this your 1st post of 8 which does infact disrespect the op and trivializes his question, while you offer nothing of relevance to it.

That hardly seems fair to the rest of us under developed wanna be racers. Asking for someones advice on what oil to use is and always will be personal preference, find someone who runs a similar combo to you and ask them what they're using and if they're happy with the results. If in fact 1320 has a similar combo and has in fact used Mobil 1 in it to his satisfaction then I retract most of my statements.Joe BTW I run Royal Purple cause I like the color.
