These threads seem to always draw a variety of opinions be they for car, motorcycle, or truck. My only point is to avoid being seduced by the sellers of ultra excpensive oils because their value is marginally, if at all, no better than products from the major oil companies. As for me, I find Shell Rotella T synthetic oil to perform flawlessly in both my motorcycles and cars over the years. Now, with my new Tundra, I plan to use it there as well. The best part is this oil is available at Walmart at a reasonable price so you don't get ripped off by the auto stores pushing the pricey stuff.
