We have just put new PC's in my 2.0 and I have been using valvoline VR1 but a guy told me yesterday that when they run in rally car engines they use a thicker oil. Does that ring any bells with you guys?

I know Penn or my VR1 is ok normally but is it better to run new pots in with heavier oil for a while?

Use break in oil to seat the rings.
Use 20w 50 when running normally.

Vr1 or penn have the correct zinc content for the lifters.
Penn break in oil also has the correct zinc content.

What's the difference between " break in " vs regular?

Lucas has a high zinc break in oil, and so does Joe Gibbs. If you want to run the Lucas, text me, and I will let you know where you can get it local.

Thanks for that. I have done a 250 mile oil change to a HPR 30 , 20/60 mineral oil from Penrite so it should be ok

Less detergents and additives. It seems backwards, but it keeps things from being too slippery. You need those parts to bed in and develop tighter clearances from the get-go, or they never will.

Irony is they used to sell non-detergent oil. Buy it anywhere oil was sold, it was budget, cheaper than "detergent" oil because they didn't have to add those expensive detergent additives. Now they call that break-in oil, it's hard to find and more expensive.

Amsoil might be another option
