Cross Breed Oil?

[bigjohn]

For the past several months, I have been purchasing the 5 quart jugs at WalMart....whatever was the best price or the best mail in rebate. Two of our cars take 4 quarts on the button. Because of my mix of Syntec, Mobil 1 and Ultra....5 quart jugs sitting the garage with about a quart in them....I lost it one day and poured them together to get rid of the excess jugs. Now I have a cross breed oil.

It is probaby.....

two quarts of Mobil 1 0W30
one quart of Syntec GC 0W30
one quart of Ultra 5W20
and....one quart of Mobil 1 0W20

I am guessing this brew is about a 1W26

So....here is the question....

Should I save this stuff to pour into my lawn mower and generator in the spring or should I use in the Accent or Yaris?

What do you think?

that's [censored] of a brew! i'd run it if your cars call for a xW-20

So Syntec and PU will help with iron wear that M1 promotes.

Both the Accent and the Yaris can do either a 20 or 30wt. So we are good there.

I guess my big question is.....different companies, different weights, etc... Having these all together....would it create an inferior oil?

Do you think I am fine to do a 6 month, 5k mile OCI?

You are fine. I've done witches brew before in my cars. Oils can be mixed. I am running a mix right now:
2 qrts of Pennzoil Platinum 5w-20 and 2 qrts of Valvoline 5w30 conventional

Next OCI will be 1qrt Valvoline conventional, 2 qrts of M1 5000 and a leftover quart of whatever SM synthetic oil I can buy on sale at the time (for oil change on the other car).

I'll run both mixes to 6 mo/5,000 miles.

Cool.....

I have another jug that is 50% Pennzoil Platinum 5w20 and 50% Pennzoil Platinum 5w30.

It will probably go into the Yaris.

I am thinking I will put the "brew" into the Accent.
