I started my engine for the first time on its fresh rebuild and it ran pretty good once I got timing adjusted. I used Lucas SAE 30 break in oil and a FL-1A filter. I’ve been told too use break in oil till 500 miles and then change it and switch to what you want, I was think Shell Rotella 15w-40 T4 as I have access to some at work. I also have oreillys conventional 10w30 I could use that I have spare on hand.
I’m wondering if I could use the T4 now right after cam break in or do I need to use break in oil still as I’d have to order another 5 quarts. It’s pretty much a stock rebuild with a MTF3 from melling and stock valve springs.
Sorry if this has been asked I couldn’t really find a straightforward answer.
Save yourself some headaches and use a gasoline flat tappet hot rod style oil.
No shelf oil with additives
No diesel oils.
No additional additives to proper oils.
Valvoline VR oil is a good choice that is shelf available.
Break in oil should be changed with in a few hundred miles max.
I recommend 100 to 150 to our crate engine clients.
