I need help with blending.

[FastGame]

I have 2 5qt. Jugs of QSUD 5W-20 that I would like to use in a motor that calls for 5W-30. The system totals 5qt. I was thinking about using Rotella T6 5W-40 to bring the QSUD up to 5W-30 level, something like 3qt QSUD and 2qt. T6. Is there a chart somewhere that will show the correct mixture ? I would be happy to hear any ideas you my have for mixing this 5W-20 to get a nice 5W-30 blend. Thanks.

The first thing you do is look up the cSt viscosity for each of the oils that you're gonna mix and then enter the numbers into this Viscosity Calculator .

60/40 blend should be in the right ballpark.

Make sure you get one of those painters sticks to stir it up real good!

If they are in your area check at Ollie's, here they have QSUD in quarts at $4.00... I picked up some 0W-20 & 5W-40 to blend a 10.9 cSt 30W using a 60/40 ratio, will be easy as it's a 5qt sump... BTW, they didn't have any 5W-30, or I would have bought that...
