I don't know where Hans gets his opinion of Castrol either. I find it odd. I don't have any experience with Castrol Syntec, but I have used "dino" Castrol in my motorcycles for 40 years and my cars for 37 years. Motorcycles got and get changed at 2000 miles or annually, and cars at 3000 miles. Now my newer cars and motorcycles are on Mobil 1. My son "the genius" says we can go 5000 miles on the synthetic. I have been trying that in the cars for the last year, but I'm not so sure. I'm not worried about the motorcycles because Triumph recomends 10,000 mile changes. My motorcycles only get about 2000 to 3000 miles a year and they get changed every April. I still like 3000 mile oil changes on the cars. Am I wasting oil ?
