What do you think a quart of MMO would do to 5.5 quarts of 5w-30? Concerned about that after some bob is the oil guy. It so freaking technical over there, you never seem like you have a yes/no although I don't have an account, just research

When I switched my 01 over to Pennzoil platinum, the first change was filthy. Then the subsequent changes were what I would call normal.

That tells me the oil cleaned some of the deposits out. I'd rather use a good oil that has a solid additive package and let it do it's thing.

LOL. Does anyone on there even know what viscosity is? For me personally the point with MMO is the cleaning factor which far outweigh any degrading of the oil IMO if it does. I've seen no evidence that it has in hundreds of thousands of miles. If anything it has more viscosity but its pretty much the same. This truck is actually the only vehicle that I didn't use MMO from the start and I wish I had. People say a lot of things its old technology etc etc. I had lunch with Elvis the other day. :lol: Gasoline is old tech. These engines are old tech. T0y0ta claims they have the latest greatest tech in their hybrids that no one else has but its the same old tech that has been around for years its not the latest not complicated not anything but BS... They just borrowed it for a car. LOL It isn't worth the worry though. If it bothers you just don't use it. But as you've seen it will be fine until the oil is changed.
