What type of oil do you use?

[Old Yeller 1970]

I really don't know if Valvoline VR1 would hurt our engines. According to the author of that thread he didn't think it had the right formulation for street driving and so could not be trusted. Others in the thread pointed out the according to Valvoline it could be used on the street. "Valvoline VR-1 Racing Motor Oil is recommended for engines burning gasoline and full or partial alcohol fuels in track and street service. Valvoline VR-1 Racing Motor Oil is for use in any car, light truck, van, or SUV where API “SM” is recommended(see proper viscosity grade below)." http://www.valvoline.com/pdf/VR-1_Racing_Motor_Oil.pdf My opinion is if Valvoline says it's good on the street and others have had good success with it then it's hard to argue against the evidence.

I live SE of Ralls which is on Hwy 82 about 30 mi from East Loop 289. Probably 45 min from Wolfforth. I noticed the trees in your avatar didn't look like West Texas trees and wondered if the photo was taken elsewhere.
Next time Old Yeller and I are in Lubbock maybe we can drop by for a visit.
