Russel,

I have forgotten what engine yu have in your vehicle. If it is a 1.9L or
2.1L WBX, multi grade oils are the oil of choice, not single grade.
Why?? They have a wider performance range that allows the to better
serve under varying conditions. For the two engines I would strongly
recommend a 20W50 st Dino oil or a 15W50 synthetic type. I ran the 20W50
Dino oil for a long time, but whn I had my engine rebuilt, after
breaking it in well, I switched to 15W50 Mobil One. I have been very
happy with it. These new synthetics hold up better, and though they cost
a little more, if they increase the life of my engine then that is what
I will run. The small additional cost of oil is insignificant if the
life of the engine can be extended by their use. There is conjecture
about that, but I know that with airplanes, piston type aircraft engines
got a substantial boost in times between overhauls when the
manufacturers began requiring the new synthetics to be use. It makes
sense to me that same life increase would occur with auto engines,
especially with the flat 4 air or water cooled VW engines. The VW flat
fours are extrordinary in their likeness to the aircraft engines and are
often used in homebuilt aircraft.
