    I'm running all AMSOIL products in mine...

    Can't tell you how it will do until I change it back out, but I've heard good things.

    When I had stock 502s, I ran Mobil One 15-50 in the motors, and I've been using The Bravo Shop gear lube for the past couple years. Currently running Valvoline VR1 Racing 20-40 in my 525s.

    For engine oils I use Aero Shell products. First as some airplane engines are high performance, Aviation oils are designed for their high performance demands. As in constant high rpm running. Second aviation oils have additives to fight moisture. I feel most oils in the retail stores are more for car engines. The higher altitude is similar to the marine environment, i.e.: moisture. Plus higher HP constant rpm running is also more like an airplane VS a car. Lastly they keep the engine cleaner.

    Not sure if it is the "best" but I have nothing negative to say about Brad Penn oil.

    Opinions will vary, and anything you buy off the shelf will sufficiently protect your engine for the long haul. However, for someone like me, sufficient is never good enough. I go straight to optimal when it comes to engine maintenance no matter if it's in my Ram, Baja, Harley, or lawn equipment. You can't buy better formulations than the "spec'd" options below. *Other Amsoil formulations can be chosen for the engine, but I said "spec'd".


    Amsoil Marine 25W-40
    - A superior 25W-40 formulation. NOACK Volatility (evaporation) of only 3.1%. That's UNHEARD of in the industry. Quicksilver specs for evaporation is "Negligible". That means "double digits" in industry talk. Max evap. to meet industry standards is 15%. You can't buy a better "Syn-blend" marine 25W-40. Amsoil also offers a Marine 10W-40 that is a true synthetic. No cheap base oil in the 10W-40 formulation, and is superior to their 25W-40 formulation. Better cold flow, better base oil, etc. Their 25W-40 only exists because some Merc owners manuals tell you to not use true synthetic formulations. Guess that's marketing lingo to sell more of their Quicksilver. In other words, I'd opt for their 10W-40 before I'd use the 25W-40. *See below

    Amsoil EaO24 oil filter - Double the filtering and oil capacity of a standard Mercury oil filter. Also uses nano-fiber technology allowing more efficient trapping of smaller micron particles without increasing back pressure. 98.7% efficient @ 20 microns. Royal Purple filters use the same technology, so do PureOil boss and Napa Platinum series filters.

    Amsoil Marine 75W-90
    - True synthetic gear oil with the best protection you can get for your stern drive, even when contaminated with water.

    I signed up as a Preferred Customer so I can buy it for all my toys much cheaper. Saves me around 25%.

    I will also tell you about the "spec'd" comment above. I prefer their Dominator 15W-50 formulation in my 496. It's a lighter 50 grade lubricant, not much greater than 25W-40, with boat loads of ZDDP anti-wear additives, yet better cold flow. It also helps when I am running the engine hard and it gets hot. I've seen oil pressure really hot at 4,800 rpm be barely 40 PSI.
