Overkill?

Engine oil with filter = 3 3/4 quarts...

 

4 on mine 91 240sx

 

Damn which is it???? That 1/4 quart of oil is really gunna mess my engine up if I put either too much or too little in. WHICH IS IT?????????

 

Drain your oil, change your filter, and add new oil. Put 3 quarts in and start the motor for 5 to 10 seconds. Turn it off and check the dipstick. Add accordingly

 

probably 4 quarts. Just do what td5turbo said. Put in like 3.75quarts and then see what it needs after that. peace

 

Should be 4 even.

 

yea one per cylinder, no?
