Agreed. Unless you are trying to set some kind of record, what’s the point of saving an extra 75 cents per month on your oil change expenses?


I believe my brother said he's capping it at 11k, but will continue to do analysis to allow a sample set to develop. I'm sure he'll have an account on here soon enough!

His results have me questioning putting syn in my own vehicle, which is older and has higher miles. It seems like a waste even though I get it for cheap after the rebates. I like to believe syn cleans better so maybe still the right choice for my own high mileage engine. These results have me mixed up about my oil choices crazy
