I use Mobile 1 and then add a quart of Marvel Mystery Oil. That stuff is AMAZING.

[jessekelli]

[jessekelli]

is it any good?/

[chefalan23]

i'm a firm believer in mobil 1. i use mobile 1 5w20 and a mobil filter every 3k. ive used that marvel engine treatment and stp treatment as well a few times. funny thing is nobody has said they use conventional. anyone else notice it acutally takes about 6.5 quarts to fill your oil?

slick 50 made a really good transaxle treatment a while back. i had an eagle talon that grinded gears so f'n bad when it was cold and i tried the slick 50 trans treatment and no more grinding. i was so impressed that i put slick 50 engine treatment in my both my cars and my boat and i lost oil pressure in all of them.

I was told the only difference between RP and Mobile1 is purple dye

funny you should say this, my brother who was a BIG fan of Slick 50 (back in the day) used it in his 30' Velocity (race boat) that had twin 502's Merc's and broke a crank in port engine and spun a rod bearing in the starboard engine.......

[jessekelli]

it seems like half the people like rp the other mobil 1, which is better??????

[fobra559]

Look at it this way, you can't go wrong with either one because no one said anything bad about both of them
