This appears to be a basic question but I could not find a straightforward answer in the archives...
I have decided to go with Mobil 1 synthetic oil for my next oil change. I recently (4.5 miles ago!) replaced the camshaft and had a machine shop redo my head (with valve seats for unleaded). I believe the bottom end of the engine has about 120k miles on it. I'll put a few miles on the car when the weather warms up and I get a brake issue sorted out, then I'll change the oil and filter.
I thought that there was only one viscosity for the Mobil 1 (I'm using 0-30 W in my new car) but I noticed that Costco sells a 5-30 as well as a 10-30 and then the Mobil 1 website mentions a 'European car' formulation. What is the best formulation to use for my car (stock 1967 B-18 with details as above)?
Also, I plan to go with the Mobil 1 or equiv synthetic for gear box (M-40) and differential. What do I need for these applications?
Any suggestions sincerely appreciated.
Many thanks,
