That's cheap for synthetic, what brand?
Diesels can actually go way beyond 3000 miles on petroleum based oil because they don't run as hot, but gas engines can't.
“That’s cheap for synthetic, what brand?”
I’ve bought Mobil 1 there for $21, $22, and $26 for 5 quarts. Recently, it’s always been $21 or $22. I always check the quantity because the price is so low - heck it’s even lower than Sam’s. I’ve got roughly 30 of the 5-quart bottles in inventory now (keeping with my plan to have 4 to 5 years worth of non-perishables - and this oil is definitely non-perishable). Heck, after reading these comments, I may buy another 20 or so, for insurance, as $50 or even $100 per bottle in the near future would not surprise me a bit, once the dollar tanks.
