i jsut did an oil change, had mobile 1 10 30 instaed of 5w30(which i am supposed to use). its been in car for 2 months now, and GOD is it pitch black!!!! i put exxon superflow 5w 30 in, car rns terrific!!! seems like everytime i do an oil change, theirs alwasy a quart missing. i have noticed a leak somewhere under car. everytime i see tiny drops of oil coming from bottom of oil filter. its splashed all over bottotm of car: ( i hand tighten my filters, use oil to lube the filter gasket. any ideas? my oil pan looks really rusted in certain areas, like the outer skin is brown and flaking off. maybe i should get that replaced hugh? car is now 10 years old.
ive decied to stay with conventional, since i use 3 month change intervals. : ) sorry abut the fram tough gurad fitler, its all the good quality stuff they had. they never have mobile M102 fitler for my car in stock, fram is the next selection they have. other than that, acdelco, valvoline, stp and motorcraft fitlers. none of which look like promising filters, to me. s thats why i stayed with fram.........for now. nextt ime, i am gunna get an amsoil filter. 13 oz. of oil a minute, and filters 7 to 10 microns!!!
