A summer (HOT WX) oil question. I have a 1991 Honda Accord with 130 K miles on it. Palmdale/Lancaster CA area gets up to 105 to 110 in the summer and I drive ~ 100 miles a day to and from work. I change oil abut every 3 K miles running Dino (Penz usually). By the way, traffic moves pretty fast out here(75+), and I do keep up . Getting ready to Auto-RX the engine, had a conversation with Frank from Auto RX today and he's seems to be a great guy. So to my question. After I get done with the clean up job using Auto RX, what sort of oil would the board recommend. I've been looking at the US version of Walmart Synth, probably a 10 W 30 or higher and going to a 5 K change cycle. Comments?
