Ran to napa today to find a bunch of old Castrol GTX startup in a green bottle for 1.50 a qt. I talked to the manager and he said he had a bunch of stuff in the back to go to clearance. I told him i would buy it all if he would take the time to bring it out.
30 qts Castrol GTX startup 10w40 ,API SL for 1.50/qt
13 qts Mobil 10w30, SJ,(old blue bottle before mobil clean) 1.50/qt
23 qts valvoline gear oil , 2.00/qt(13 synpower, 10 regular), various weights
9 qts valvoline engine treatment, 1.00/ qt (looks like oil container)
Gear oil was a great find the synpower is about half 75w140 and other half 75w90 and the dino was about the same split between 80w90 and 85w140
I actually dont even know what the valvoline engine treatment is but the instructions say to mix 25% and run with oil change interval similar to MMO.
Grand total about 130 dollars out the door. The GTX startup data sheet is about worthless. Does anyone have any idea what this stuff is or its viscosity?
