Hello S77


The reason any vehicle burns more oil than it should is because the rings around the pistons are worn, broke or just bad. When you have bad rings the oil that is lubricating the engine is allowed to creep up into the expansion chamber where the spark plug explodes the compressed gasoline which forces the piston down. When oil has compromised the expansion camber the spark causes a type of smoke which would be bluish gray if this is the case. There could be other internal problems such as valve guides but either way you have internal problems. As long as it's not a oil leak that's drip onto the exhaust system while driving and shows no ground drippings. Good Luck BSWhy does the '02 nissan frontier motor burn oil?
What size 2.4 liter or 3.3 liter V-6? Oil consumption is something Nissans do not do. Unless there has been abuse like lack of oil changes, overheated or running with out an air filter element.
