I hear Royal purple and Redline, are two of the best, I use Mobil-1, because I get it free at my job, and change it every 20 hours, so far so good,

Unless you're bad about changing oil with frequency, there's no benefit whatsoever to using synthetic oil. Synthetics don't break down as quick because of their tolerance of higher heat levels.

The real question concerning synthetic oils is with their lack of resistance do they help provide an extra rpm or two in if used in the outdrive? With their high heat resistance are they not better suited for the outdrive than they are for the engine (unless you're frequently late to change it)? These are the real synthetic questions to be pondered......

Reckless,

On my hotrodded outboards (9000 rpm lake racers), not only did Amsoil give me 200 rpm, the gears stopped eating themselves. With Merc conventional gear lube, the gears lasted 10 hours the first time after a rebuild. Second rebuild was checked and rechecked and lasted maybe 15 hours on conventional lube. Third rebuild was checked and rechecked and Amsoil was used. Those gears are still in it (in a barn) I probably ran it another 70 hours after that last rebuild. No particles in the lube and nothing stuck to the magnet.

Not selling Amsoil - I feel that all name brand hi-tech synthetics are absolutely THE stuff to use in anything that is running close to the edge.

mcollinstn you make my point. I believe all the yap about synthetic in the engines is misplaced as per my comments above. I think synthetic oil's real benefit to the powerboat community lies in the outdrive...

The man who builds my motors, marine & auto, showed me the inside of two 358 modified motors after one season of racing... one used Mobil 1, the other Castrol , I use Mobil 1 based on what I saw & his advice.... he does NOT recomend synthetic in Blower Motors... I don't know why for certain, but I believe it had to do with bearing wear? I use NAPA racing filters... so far so good!

I look at it like this. Mobile brings it right out of the ground to the finished product. I think they understand oil as well if not better than anyone out there.

The product has never let me down.

1999 Baja 454 150 Hours
2000 Baja 502 Mag 200 Hours
2002 Baja Twin 500 EFI's 78 Hours

I have had NO failures and have no reason to change.

Good Luck
