After DQ got me motivated, I’m changing the oil in most of my old car’s next week. The oldest oil is in my E9 (7-8 years, about 1000miles), the next oldest is 2.5 years old and 1800miles (XK120). Race get fresh fluids every 4-6 hours. This excludes a British street engine that leaks 1 qt per 500 miles, essentially ensuring the oil in the sump stays fresh. On that motor a yearly filter change seems sufficient.
Anyway, I use Valvoline VR1 20w50 and Brad Penn. Currently the Valvoline is on sale for $3.50/quart, which is about 1/2 off the usual price at my locally owned car parts store (think global, support local).
I have not seen quality motor oil this cheap In more than a decade. Perhaps it’s a related to the recent crash in crude oil prices.
I don’t know the shelf life of motor oil, but I bought a substantial quantity. Even if I become religious with yearly oil changes, I’m good for a while
