In which season is 5w30 used in.
the idea is that the bigger the #, the thicker the oil is. in summer, thicker oil is better i think. but it also depends on the condition of your engine. if it leaks or burns a lil oil, its better to go with thick shit cause it seals better.
my civc burns it, lady before me used 10-40 and i use 20-50 and add a lil more than a quart about every gastank at work.
off topic, is that really bad? when i get on the gas high in the rpms, which i dont do much cause it doesnt go any faster since its the weaksauce d15, blue smoke comes out. when i got the car, i cleaned oily residue off the rear bumper. it hasnt built up again yet. last time i added oil, i went nearly 300 miles, pulled my car into the bay and added nearly 2.5 quarts! it has to be burning it cause its obvious, the more i drive, the more oil disappears. is this something serious? or can i just keep addind oil every week/whenever its low? i dont mind it cause its free from work
