So while you are putting some brand of oil in the motor (assuming you change your oil) I haven’t got many answers on brand weight and why.doesnt matter if its flashing and bold and font size 80. people will still ask and not use the search and if its something they dont like to hear they go ape shit.
I have been a BITOG Member for 20+ years. The B58 discussion focuses on oil weight. My question is what brand, what weight, and why. For example, I will 1st try Valvoline European 5w-30 because it is an SN grade low Sap’s oil with good anti wear additives package.(~1000ppm ZN,PO, 200 BO, 1000 ppm CA, and virtually MO.) I will monitor oil temperature, consumption, and the general feel as to how the engine runs at low and high rpm. If it feels good. I will have a VOA and UOA sample analyzed for wear metals at 1000, 2000 miles, …. If it doesn’t feel right, I'll drain and go to another oil like Mobil 1 ESP, Castrol Euro, Amsoil, motorcraft, …
I asked the question because of all the experience you all have with your Supra’s. Lots of folks are using liqui moly. Why?
