Mixing Rotella triple protection w/ Rotella T6

[TexanLorenz]

I'm changing my oil and want to know if putting in about 4 quarts of triple protection 15/40 and filling the rest with T6 5w40 is a bad idea? I want to switch over but want to use up the rest of my triple protection. Thanks

I wouldn't do it.

Would it hurt anything? probably not, would I do it to my truck and therefore reccomend it for anyone else? probably not lol, but really these 6.0's are so picky, I would bite the bullet and do all t6

It'd be fine if you really want to do that but I'd avoid any Dino oil at all costs if i could.

I have run dino oil since the day it rolled off the lot. Oil analysis always come back clean. I am at 133K.

Congrats. Come back and let us know when you have to replace your injectors.

Ryan, use the 15w40 in something else. A gallon of T6 is $23 and change. If you just have to add the 15w40 go ahead but change the oil in 5k miles.

Thank fellas for the info. I'll go ahead and fill her up with t6. I'll give the triple protection to my dad and his f250 6.9 liter.

ok, how long do injectors last on dino oil?

Every example of a bad injector can not be placed squarely on the trucks oil. Fuel pumps go bad, bad fuel, fuel filters not working, etc.

Someone that reads all these doomsday posts might suffer a panic attack. Truth is, there are a ton of these trucks rolling around, some with ****ty maintenance and they still ride out. Sometime you get a good one sometimes you get a turd.

Really we are affraid of 4 quarts of oil?

i am sure the other 11 quarts of high tech synthetic will be ok for the next 5,000 miles.

^^ I agree. Mixing one gallon of 15w-40 with almost three gallons of 5w-40 should give you the cold flow properties close to a 10w oil...still a little under than. Given the fact it is the summer...I wouldn't worry.
