I picked up 7 Quarts of Pennzoil 20w50 at Napa recently for 3.79 a quart, my old bimmer takes about 6.1 quarts. Thinking of going for a mix of four quarts of 20w50 to two PP 10w30s Thinking of running a 3750+ oci with this possibly.
Kind of conflicted because on one hand I feel this is a good idea for good cleaning properties of PP, but also concerned it would dilute viscosity too much for the engine. 15W40 is lowest viscosity I run since Louisiana winter isn't all that cold typically, but it runs very well. Looking for input on if this would be as thick or thinner than 15w40 at a 4/2 20w50 to 10w30 mix, I forget how to calculate those figures.
Thanks.
