Almost 99,000 miles. I still use the cheapest 5W30 oil I can find that meets the SAE spec. Well ok, I did pay $12.00 for a 5qt bottle of Pennzoil Highmilage the other day. There was something for $10.99 but I said, what heck, I'll buy the good stuff this time. Walmart has the best prices.
I'm thinking about using there oil soon.
