Valvoline Oil Blend

[rdnck_grsmnky22]

I have a couple questions about a blend i concocted using two different valvoline motor oils,to resolve a low oil pressure issue and correct it in a 1988 Toyota 4x4 Xtra Cab V6 3.0l 3vze engine equipped pickup truck,i mixed 2 1/2 quarts of valvoline vr1 racing 20w50 conventional motor oil with 2 quarts of napa premium conventional 10w30 motor oil (napa premium is made by valvoline),and i was wondering what viscosity i should have with this mixture,it brought the oil pressure up alot,and reduced valve ticking noises by 90%,and i was curious if this oil would be suitabale for year round use. It gets cold snaps down 15 - 20* f here in the winter on cape cod,i am guessing this is about a 15w viscosity blend. Input appreciated,sorry to be so long winded

Sincerely,

Pete the redneck mechanic

15W-40

Would it not be cheaper just to buy a HDEO 15w40 like Chevron Delo, Mobil Delvac, or Shella Rotella for $6 a gal?

Routine starts to 15&#176F

Occasional Starts to 0&#176F

As noted, you probably have a 15w40. Why not run Durablend 15w40. Or you could run a 10w40. They're pretty good these days. If you want HDEO additive levels, see if you can find Citgo Ultralife (high mileage) as it comes in 10w40, is nice an thick and loaded with zddp and has moly too.

If you had some information on the Napa oil, we could tell you exactly what viscosity the oil mixture you're currently running is.

Regardless, I'd take an already formulated 15w40.

I'd suggest Mobil Delvac 1300 Super.
