[QUOTE="Bill Ellis, post: 531813, member: 59929"] 0W20 vs 5W30 has nothing to do with the change interval. Oil does not "break down". Rather, the additives that suspend dirt and counteract acids do become depleted in all oils. In general, synthetics have longer service life because they do both of those things longer than dino oil. Chances are, for normal driving, not towing, 0W20 probably won't hurt anything. But, note the word "probably" here. If you use it and all is well, you'll find out that it's OK. However, if you fry your engine due to lower than recommended oil viscosity you'll find the cost of a new engine to be a lot higher than those cases of oil. If you live in a cold winter climate, use it then but only if you are doing normal duty driving. Many here don't remember the days of single viscosity oil [10W30, etc, weren't around yet] when we always put straight 5 or 10 weight oil in the engine. 20 years ago just about all engines used 10W40 oil. Now, with better materials and closer tolerance fits, most engines use 5W30 or even 0W20. I suspect with the Mobil 1 you would have no problem as long as you do normal service driving.
