I did this in my old Sentra, two quarts good dino oil and two quarts mobil1 (before they changed the formula).
If you guys are running synthetic, be aware they aren't the same. Most store bought synthetics are base3 stock and provide a little more benfit than dino oil. Things like Mobil1 EP are made from base4 stock and are what most people have always thought synthetics to be. I run mbile1 EP in my Sentra and grand national. The sentra because it turns at 3500rpm for two hours at a time and the grand national because the oil won't coke in the turbo when the engine is shut off and because of the zinc issue ataylorracing pointed out.
