I would guess that everyone probably has thier favorite brand of engine oil but I am wondering if there are any experiences or factual reasons why one brand is better (or not) than another. I currently have a independent service shop putting in Elf. Cost is about $100.
I checked with the local dealer and they will charge about $100 and use Castrol. They will also do the other checks such a fluids and rotate tires - something the independent did not do last time.
The only other difference is the dealer is much closer (5 mi versus 30mi). The Treg has 80K on the clock and oil checks show a remarkably clean oil.
Thanks in advance.
