AMSOIL Synthetic 5W-50 ATV/UTV Motor OilA reader asks: I’ve got a 2016 Polaris RZR XP Turbo EPS. Have you got a synthetic 5W-50 engine oil that is suitable for this turbocharged motor?

Our answer: Yes we have a synthetic 5W-50 that as engineered specifically for heavy-duty and even turbo-charged Polaris engines.

A reader asks: I’ve got twin 2013 Mercury MerCruiser 8.2L H.0. MAG inboard engines in my boat. This engine does not show up in the AMSOIL application guide. Can you recommend an AMSOIL motor oil and oil filter for this engine?

Our answer: While it’s true that MerCruiser engines are not included in the “Marine” section of AMSOIL’s online application guide (for some reason), we can provide a couple of motor oil options as well as an oil filter recommendation for your 8.2L H.O. MAG engines.

Engine Oil Options

AMSOIL Synthetic-Blend 25W-40 Marine OilThe first option we would suggest is AMSOIL’s brand new Synthetic-Blend 25W-40 Marine Oil. This motor oil was engineered specifically for Mercury/MerCruiser motors. Marine engines are routinely put under tremendous strain and this new 25W-40 is designed to provide consistent and long-lasting wear protection. This AMSOIL 25W-40 is a cost-effective upgrade for Mercury Synthetic-Blend SAE 25W-40 Marine Engine Oil.

If you would prefer a 100% synthetic option, have a look at AMSOIL 10W-40 4-Stroke Marine Synthetic Motor Oil. This 10W-40 is a highly suitable replacement for any 25W-40 marine oil. It offers all of the wear control, shear stability and extreme heat resistance required for your MerCruiser engines in a high-tech, full-synthetic package. If you want a full-synthetic oil over a semi-syn for your engine, this is your best bet.

Does AMSOIL Offer A Full-Synthetic 25W-40?

AMSOIL offers only the synthetic-blend 25W-40. Mercury markets only a semi-synthetic 25W-40 for their engines, so AMSOIL wanted to provide a product that was easily recognized as a Mercury alternative. There is absolutely no technical reason to use only a synthetic blend in these engines. We’re quite sure that Mercury did this to keep motor oil input costs down. Prior to the release of this new AMSOIL semi-synthetic 25W-40, AMSOIL suggested the 100% synthetic 10W-40 4-Stroke Marine Synthetic Motor Oil for all Mercury applications requiring 25W-40 motor oil. The 10W-40 is an outstanding shear-stable option, but as Mercury owners were looking for 25W-40 and were unsure about a 10W-40 (despite the fact that it is an outstanding substitute), AMSOIL created the new 25W-40.

The bottom line is that either option is perfectly fine. Have a look at our pricing and choose from there.

Bypass oil filtration has come a long way since the days of toilet paper being used as a filter element. As with any bypass oil filter system, a small portion of the engine oil is slowly run through a very fine filter element. Except in that case, ordinary single-ply toilet paper was used. We aren’t kidding. There are still systems on the market today that use toilet paper to filter engine oil.

AMSOIL’s bypass oil filter systems have never been suitable for bathroom duty. They use a very sophisticated filter media which leads the market with exceptional filtration efficiency, dirt-holding capacity and durability. Now AMSOIL has released two new systems that make for easy installation on Chevy/GMC Duramax diesel engines and Ford PowerStroke (6.0L and 6.4L) diesels. These oil filters systems remove soot and dirt down to less than 2 microns for extended oil life and reduced engine wear.

Oil Bypass Filter System For Ford 6.4L/6.0L PowerStroke Diesel Engines

AMSOIL BMK-31 Oil By-Pass SystemThe new BMK-31 for modern Ford PowerStroke diesel engines is a single remote bypass filter. This means that a single bypass filter is employed, while the factory full-flow oil filter stays in place. The BMK-31 kit comes with all of the parts, filter base and spin-on bypass filter, hoses and fittings needed for easy installation. An ingenious billet aluminum full-flow oil filter cup replaces the stock unit (note the right-hand item in photo). A fitting on the end of this location draws a small portion of engine oil out of the full-flow oil filter housing and runs it through the bypass oil filter. The ultra-clean oil is then returned to the engine through a custom billet oil filler cap. The fit, finish and construction of all of the components of this kit are truly top shelf.

New Oil Bypass Filter System For GMC/Chevy 6.6L Duramax Diesel Engines

AMSOIL BMK-32 By-Pass Filter For GMC/Chevy DuraMaxLike the Ford system, the BMK-32 system for GM Duramax diesel engines is an easily installed single by-pass filter system. In order to draw oil from the engine, AMSOIL uses a clever billet aluminum “sandwich adapter” that fits between the engine’s spin-on full-flow oil filter and the filter base (note the right-hand item in photo). Oil is drawn through a fitting on this sandwich adapter, passed through the oil bypass filter and then returned into the engine through a billet aluminum oil filler cap (that has a return fitting on top). The filter base, bypass filter element, hoses, fitting and parts are all included in this kit.
