Oil Spec

The engine arrived safe and sound. Looks great and that's a big understatement. I have one question; I have had great success using Mobil 1 in my small blocks, any reason to think differently about the 427? I imagine there are others that would like to know.

Thanks, Tom.

I don't see any reason to think differently about our FE's. I would wait until the rings are seated of course, but I think Mobil 1 will be fine, long term. So far every customer I've asked about what they run for oil has given me a different answer.

Chris: I am using the Union 20W/50 you folks recommended and plan on changing to synthetic oil when I get to 1,000 miles. I do have a couple of oil drips that appear to plague FEs, even the new aluminum ones, like mine. I was told that as I got more miles on the engine the leaks might stop, especially on the rear main. Well, I now have about 600 miles on it, with no changes. Is it going to get any worse with synthetic oil? Even though I don't think much of Exxon as a corporation, I am thinking seriously about using Mobile 1. Thanks for your help. Rich

I think that would depend on the severity of the leak. Do you know where the leak originates from? Maybe it can be resolved and turned into a non-leaker even with synthetic oil.


P.S., your Exxon statement made me laugh :)
I feel the same way when I eat Nabisco (RJ Reynolds) products.
