Re: Which oil should I use?

A quality 10 W 30 will do fine.
After a 500 mile break-in, drain and refill with the same.

If you drive a lot in hot weather, a 10 W 40 is a good choice.

I'd use conventional 10 W 30 for break in, then go to a full synthetic 10 W 30 or 10 W 40.

I'd change oil every 2500 miles with conventional oil, and every 4,000 miles with full synthetic, unless you drive under very adverse conditions.


I run a Model T Ford on 10 W 30 full synthetic. It works great in any weather.

This Model T will easily do 46 to 50 MPH, and I often drive it over 40 MPH, and I have put many thousands of miles on it with no issues whatsoever.
