I personally wouldn't.

 

I may just drain 5 quarts and refill in a few hundred miles so it'll be really diluted and hopefully things will be clean. Definitely quieter but lower viscosity is a concern with it be super hot

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.

 

I think the first owner wasn't as clean as I am so just tidying up

Yeah I mean it probably won't hurt anything. Just wouldn't be my personal method.

Gotcha, I've got a little bit of MMO remorse

I wouldn't worry about it. If you are worrying about it then like you mentioned, let it in there for a couple weeks then change the oil again.

 

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.

 

The increased heat caused some concern but no more. Thanks!

Oh yeah, I've seen 120s there in the desert. Are you west or east?

"West" Texas which is close to Abilene.

Couldn't take the current Phoenix heat. How do they do it? How do they keep from overheating and frying their transmissions?

Well the truck running around 195 still has quite a bit of difference still if the radiator and cooling system is sized right.

 

If you spend any time over at BITOG then you would know what oil is higher in cleaning abilities and you would know a couple of short OCIs is all you need.

Not enough time apparently, care to enlighten? Would be appreciated!

Yeah,... I'm going to have to just go ahead and disagree on that o e.If that the case it's not really very dirty in the first place. Just change the oil interval or oil.

 

The OP is one over concerned dude when it comes to maintenance on his truck. If you have seen some of his other posts it borders on paranoia.
