With all the different 1800 engines (b18s, b20e/f), does enyone know the the gasoline grade requirement for each? Should you use 87, 89 or 93, or does anyone know where to find the info.

Seems simple, but I can;t find it:-)

Thx.............

To me, when you consider all the variables such as;

Age
Carbon deposits
Different production dates
Repair history - (Which engine do you really have?)
Tune up variations
Carburator adjustment
What fuel did you really get?
How many miles do you travel?
Are the quality miles?

and about ten other things...

I'll feed my older Volvos (actually all of them) high test.
