oil brand
 

I use and recommend BRAD PENN racing oil.

It's got enough ZDDP to suit me.

20-50 for drag racing.

Nitro 70 for blown alcohol pulling trucks.

This stuff is also so "clingy" its tough to clean off engine parts.

Hell put some oil in her and let it ripp :lol:

I use vr1 20/50 with dry sump.... 35psi idle and around 75psi thru the traps

Going with the Schaeffers oil 20/50 no blend.

good choice, very high zinc oil

Re: oil brand
 

When do you use a straight weight oil such as 50 or 60? I don't understand what the diff is from a 50wt -VS- a 20/50 for example. I see you use it in the alcohol motor...

Here is a good read for ya to explain it at bit, most people have no clue what W even stands for.

Hey David,

I finally took the time to read the article w/o being interrupted. I understand now. I like the viscosity of a straight weight oil such as 50 or 60; but with a really good additive for cold starts. On an older engine, it seems like a good comprise in Spring/Summer in my CJ7 w/ Mopar 360 (mildly built). I see good OP @ OT & idle, but I also have a little security in those oils when the temp is quickly fluctuating like Jeeps can do. The motor is broke in well & probably has pretty big bearing tolerances- oil pressure w/ 10/40 @ idle bugs me too much when I look at the gauge & see 8lbs... I guess it is part mental too.

Ain't it fun to learn sh*t?

Love this forum . .

RK: INDEED!! I have learned so much from these dudes.... I got all my carb knowledge here... sometimes at 1AM in the morning. Other times, RJ saved me much pain in the wisdom gained.

I know what the W means im a winner :lol:
