Hey guys, i know im over thinking this a little but isnt that the fun of this forum?

I am getting ready to change the oil on my ls1. Its in a weekend fun car so mostly sits in the garage except for weekend drives and a handful of track days per year. Maybe 2k miles a year but sees will see high rpm usage, 4-7k constantly for 20 minute stints this weekend and makes about 425whp.

Oil filter fram ultra
Id like to get rid of some of this vr1 if its possible. Or should i just avoid it..
So far the Normal oil has been M1 ow40 with great results but dont have any right now.


What i have in my stash now:
3qts vr1 syn 20-50 sl
3qts vr1 syn 10w30 sl
3 qts vr1 dino 50 (states exceeds sn/sm/sl )
4 qts Val syn HM 0w-20
4 qts val syn 5w-40 power mst
4 Edge 0w40 sn
6 edge 5w-50 sn
8 M1 15w50 sn

thanks!

I guess I'd use the Edge 0W40 up and finish the fill with the 5W50.
If you're not planning to run it all when it get really cold, then the M1 15W50 would also be a good call to my way of thinking.

The valvoline 0w-40 MST is more like the M1 0w-40 (high calcium, no magnesium, plenty of Mo/B).

The 0w-40 Edge is a low calcium, high magnesium oil. If you've had good luck with the M1 0w-40, then try the Valv-MST next. Not familiar with the VR1 oils, but maybe mixing in 1-2 quarts could be ok...especially just before a track day.

That's where I would have gone...

Then 2 changes of (trying to cut back the VII a little bit with a shear stable mono)
3 qts Castrol 5W50
2 qts Castrol 0W40
1 qt Valvoline straight 50

Then
3 qrts VR1 10W30
3 qrts M1 15W50

Then
4 qrts MST 5W40
2 qrts M1 15W50

leaves you (if I've done the math OK, one 0W20 and 1 15W50)...mix them now for top offs...

Seriously, I'd do a Sasha Gray blend, mix them all in a bucket, so that they are all the same...

Despite the same mfg name, I think those have very different add packs...one without sodium, and one with sodium.

Mix the 20w50 vr1 with the 10w30 vr1 for one fill.

Mix 3 qts Val 0w20 syn with the VR1 50 for another fill.

Mix the 4 qts Val 5w40 MST with the last qt of Val 0w20 for another fill. Sweeten this fill with M1 15w50 to top up.

Mix the 4 qts of Edge 0w40 with 2 qts of Edge 5w50 for one fill.

Buy thinner oils to mix with the remaining 50-weight Edge and M1.
