What kind of oil is everyone using with their hydraulic roller cams?
And it smells like popcorn when it burns! LOLMazola. Corn goodness.

IMO it depends on the rest of the motor.
If it's an older LA converted to roller I would say 10/40 or 20/50
A newer motor like a magnum then around 5-10/30 full synthetic.
I run 5-30 Castrol Syntec in my Magnum because it was machined for synthetic when it was made.
I like to run an oil viscosity that when at temp running down the road my oil pressure is around 5-10 lbs less than the cold start pressures.
This tells me I'm not letting oil bypass, and that I have a good amount of flow through things.
My thoughts on it are a little lower pressures at temp because of a thinner viscosity means the bearings are getting the best flow of oil through them.
I firmly believe flow volume is more important than pressure.

I have a 92 LA block converted over and run VR1 racing oil 10-30What kind of oil is everyone using with their hydraulic roller cams?
Old LA block.
It depends on the lifters. Some tight tolerance lifters don't use viscosity ratings for oil recommendations, but instead use a centistoke value. Try to find an oil with a centistoke of less than 100, and it should work for most lifters on the market.What kind of oil is everyone using with their hydraulic roller cams?
I've got an LA roller too. All putting it together, but I'm going after break in I'm hoping I can run 5 or 10w30 full synthetic. I've got factory spec bearing clearances.

oriellys brand (which is recycled valvoline oil) 5-30
Lol yeah I remember my boss saying something like thatO'Reilly brand IS Valvoline, but it;s not recycled.
