merc lower oil usage

[intrepid]

Hi<br /><br /> I've got a question concerning my 3.0 lx and the lower oil type.<br /><br /> Merc has 2 types , normal and hign performance oil.<br /><br /> One cost some much more than the other.<br /><br /> Which would you use and when?<br /><br /> or is there a product in the aftermarket that is just as good?<br /><br /> thanks

Re: merc lower oil usage

After reading many different articles, I use the cheapest thing I can find that has the SAE & API ratings. I run pretty hard sometimes & then it seems like she just sits. I trailer mine every where though. If yours sits in the water all the time little more cash may be worth it.<br /> Most of these companies have their oils blended by the same refinery. I have also used AMS oils there are expensive though.<br />Butt everyone has an opinon about oil it seems like.

Mercruiser suggests using only the high performance in their out-drives (they also only ship drives with high performance lube in them). I have seen people put the regular stuff in the drive, and in just a few trips it comes back all burned and black (the stuff even smells burned).<br /><br />The green/blue high performance is much better, doesn't burn up, and is (as has been said by mercury) able to still reliably lubricate the drive even with 25% water contamination.<br /><br />Scott..
