We're really branching out on Hometalk! I am no expert but my car geek and former Porsche racing dad always suggests high-quality synthetic blend motor oil for my Honda, which now has about 180,000 miles on it.
We use Synthetic oil in all our trucks, we do not own a car. all have at least 100k on them. One has over 275. Do not smoke, burn oil in any way.
The only thing I would suggest is to read the manual and see what they suggest.
I always use synthetic oil in all of my trucks and have had great success. When there is a viable gas alternative I will switch to that for fuel.The faster our country can become less dependant on others, the better.
