Mix Redline 5W30 with 0W30

[magnus308]

Hello all,

I plan to do an oilchange on my Volvo soon and i have 3 bottles of Redline 5W30 and 3 bottles of Redline 0W30.
My car runs great on both the 0W30 and 5W30 but i want to use the oil i already have and then it would be a 50/50 mix of those since my car require approx 6 quart bottles.
Would it be ok to mix them like this?

I quart of Redline costs 35 USD here in Sweden... Thats why i want to use what i already have.

I'd use it. It should be fine.

Yes, I recall Dave or Roy from Red Line saying it is OK (and sometimes desirable) to mix their different viscosity oils.

Yes, you would pick up the benefit of the higher viscosity index number from the 0w30 (it will raise the whole mix's VI# significantly, and slightly lower the HTHS number of just the 5w30), which will help your cold starts in your not too very warm winter there.
