how many of you would recommend seafoam

stevo9389

if it doesnt look like pudding under your valve covers i wouldnt worry about using seafoam. does your oil come out dark black when you change it?

seafoam is good to suck up in a vacuum hose for top end cleaning. Leave it out of your gas, and with good API SM oil (conventional or synthetic) it's not going to clean a whole lot.

as long as you change your oil regularly and dont buy a no name brand you will be fine. filters, stay away from fram. ive been happy with castrol products. i noticed that since i started using Castrol Edge my pressure has been higher than it was with conventional

My lt1 holds anywhere from 30-70 lbs of pressure. I run Mobil 10-30. It has developed a sort of knock when you first fire it up. Is that because its like 30 outside or should i start to worry?

probably just the oil being extremely thick from low temps and not flowing through the engine quickly.

Mobil one 10-30 full synthetic for me. Valvoline full sythetic was my first choice but the engine used at least a full quart more of oil in 3k miles than mobil one. Disappointed me, just my observations.
