Hey guys . I'm going to drain my current oil in my 4 cyl SE (Valvoline Racing 0w40 regular oil) and replace it with Mobil 1 synthetic and Mobil 1 filter. Now here's the question. I'm thinking about using the high visc. Mobil1 15w50 ..... any objections with that? Other than that, Mobil only makes 30s 0w30 5w30 10w30 Why the hell don't they have MORE SELECTION?? My engine has milage on it and oil pressure hangs on the L of "normal" so I don't want a real watery oil.... Let me know what kind of oil you guys use currently and your thoughts on me running mobil1 15w50 in my engine. Thanks. - Sergio 93 Probe SE 5spd 97,000+ fast driven miles. > -- > >

i run mobil one 10/30 in mine with a bosch or deutsch filter dependin on my mood the day i buy the stuff but i wouldnt go 2 thick u may end up starvin the engine on the start up after it sits for a few hours and thats not good either

I use castroil 10W 40 with a napa gold oil filter it is just up to the person and the type of area they are at also.
