This is the oil we recommend for breaking in flat tappet & hydraulic roller cams.

Remember you will need enough for two complete oil changes & two filters.

Even if your engine normally uses 10W-30, the 10W-40 works excellently for break in. 

Full break in procedure available on request

We are addicted to buying old junk. Jeeps, Tractors, Heavy Equipment it doesn't matter to me as long as it's interesting & old. Share in our adventures as we get this stuff running, driving & sometimes even restored.
