Made a run to my local dealer today for oil (they have been selling me oil and filters at a good price). Parts guy says no oil and there is a national shortage, been backorder for 45 days. So called the other toyota dealer, same thing. Called Lexus dealer and was able to get 14qts. But paid full price. Lexus parts guy was telling me there is in fact a shortage of 0w20. First I've heard of this. I try to stick to the toyota oil. Anybody else been ha ing trouble finding?
