Guys, have a 4.4L jug of 0W20 Mobil 1 AFE. I want to add 1L 5W50 Mobil 1 and hope to get close to a 5W30
Any way of doing this math?

If you know the cst, use this: https://www.widman.biz/English/Calculators/Mixtures.html
Edit: I did the math and you would end up at 9.83 cst @ 100c which is a 30 weight.
For low temps you would be between 0w and 5w.

Awesome! TKS
Assuming similar base oils I get 9.9 cSt using my calculator:

I get 9.84 cst at 100c with the 0w20 at 82% of volume, ans the 5w5 at 18cst.
So close enough.

The M1 FS X2 5W-50 has actually KV100 = 17.1 cSt. That gives 9.86 cSt for the mixture/blend, rounding off to 9.9 cSt.
The M1 FS X2 5W-20, like all M1 FS and ESP oils, is a Euro oil; so, it has an ester (POE) content of 5 - 7%. Since this is a small percentage, alpha in the formula should be close to 1, and the viscosity of the mixture/blend should still be close to 9.9 cSt. For a more ester-heavy oil, it could be slightly above 10.0 cSt.

It's coincidental that this came up as I've been contemplating a Mobil 1 mix for my next OCI in my 2014 Focus.
I have 3 qts. of 0W20 (older SM) and i was planning to add 1.5 qts. of M1 10w30 for the warmer weather....It will come out as a thin 30 wt. or a thick 20 wt.....whatever.....I'm doing the mix because I don't have enough 0w20 SM...and I have 2 qts. of 10w30 SM....so it should be fine.
I know Mobil stated that mixing M1 was OK....Does anybody think mixing would shorten the OCI length capabilities?

I mixed 50/50 Mobil EP 5W-20 and Mobil 1 HM 10W-40 to obtain somewhat of a 30wt. Has been running fine in my LS3 Chevy.
I never had any luck when I made dumbell blends. Maybe never hit the right combo.

I've been mixing oils to get what I want for my wifes S2000 for 160k miles. I'm running 4 qts. of M1 0/40 fs and 2 qts. of M1 racing 0/50 for the last five(5) 7500 mile oil change intervals. Before that I ran (SM)M1 HM 10/40 and V-twin 20/50 at the same mix ratio. With piston speed up at F 1 levels and witness to over 10 engines that have gone boom on the track and/or street, I wnat to make my wifes car last as long as I can, its way cheaper than buying a new toy for the wife. I also know of some older ZO6 Corvettes that run a 50/50 mix of M1 0/20 AFE and M1 Racing 0/50 oil with good results that brought down metal numbers.
