I turned on my car today and noticed there was some slight smog coming out of my exhaust so i turned off the motor and checked the oil. The oil was below the bottom dot...there was hardly any in there! I've been waiting to change my oil when i do my turbo install in a week cause i have to drain/tap the oil pan anyways and i didn't want to waste a 5 quart thing of mobil 1. I ran to walmart and got some castrol gtx (my friend uses it on his maxima and he says it's ok) Put a tank of stp fuel injector cleaner and filled up with exxon 93 octane. It seems to run much better, but have any of you nitrous guys noticed that the motors burn a lot of oil? I filled up maybe 1500 miles ago cause i noticed i was a bit low and i guess it burned it all up. When i emptied my dirty oil out i poured it back into the big 5 quart container to check how much and i only had 1.5 quarts left....the car takes 3.5. Hopefully i didn't do any damage, it idles/drives fine and i only use 93 octane gas. I think our cars also have an oil pressure warning light and mine never came on so i don't know what the deal is.....
