Any opinions on these high mileage oils? Do they really do what they're supposed to?
quote:My car is using oil, about 1 qt / 850 miles with the 5W30 or 10W30 the manufacturer specifies. I tried Castrol high mileage 10W40 and it went to 1 qt / 1,050 miles. Now I am using Roetella T 5W40 and getting about the same 1,050 miles / quart or maybe a little less usage than that (have only had it in a short time). My concusion is that the "high mileage" features of the oil didn't do much to help me. Supposedly it is on the higher end of the viscosity range (which I verified as true through UOA), less prone to evaporation and has ingredients that are supposed to be good for you seals and gaskets. Many people on here claim to have benefitted from the high mileage oils. I personally did not experience any benefits, as far as I could tell. They are a lot more expensive, so I would only continue their use if there is a significant quantifiable benefit. [ May 31, 2003, 05:54 PM: Message edited by: CJH ]

quote:Domonic, yes, you are right of course...although some people claim minor leaks have been eliminated by using high mileage oils. I do think there is something to them...try it and if it helps, go with it. But if you try it and see no benefits, what is the point?

quote:If it doesn't burn oil or leak oil, I have to wonder what your motivation would be? The way I see it, the benefits are: 1) viscosity at high end of range for that particular grade, 2) has ingredients to minimize evaporation and 3) has ingredients to condition seals and gaskets. So if you are not consuming oil by burning or leaking, why would you choose HIGH MILEAGE oil?
