HP Marine Synthetic 2-Stroke Oil (HPM)
High-quality motor oil is critical for maximum performance in modern two-cycle marine motors. Direct fuel injection (DFI) improves combustion efficiency, delivering the extra power enthusiasts want, while leaner gas-to-oil ratios provide the reduced exhaust emissions the government mandates.

I would buy it againGreat product. It's nice not getting smoked out when slow trolling Item Reviewed: HP Marine Synthetic 2-Stroke Oil (HPM)
worth the extra moneyEven thou my old Suzuki 2 stroke does not require this more premium oil. It makes it run much better. The plugs do not foul out and the motor runs faster and smoother! I believe it is from the extra cleaners in this oil. Over the years of using non-synthetic oil the rings and reed valves became sticky and now they are free moving. Worth the extra money.

Best 2 stroke oil madeI have had 15 different outboard engines over the years. I started running this oil 3 years ago in a Johnson 75, 1981 model. The cheap oil kept fouling bugs every 90 days due to carbon build up. I switched to the factory synthetic hd50 and plugs lasted 6 months but still smoked a lot. Changed it to amsoil and smoke stopped and so did the carbon. Plugs were now changed at 1 year but didnt need it. Compression numbers stayed the same for three years. Now I have a merc 115 that I'm switching from their factory semi synthetic oil to amsoil. Item Reviewed: HP Marine Synthetic 2-Stroke Oil (HPM)

Buying it again.I was in need of two stroke oil for the start of my bass tournament season. After speaking with a buddy who is also a bass fisherman he is also a dealer of Amsoil Products. He convinced me to give it a try. I've burned through two and a half gallons of the HP Two Stroke oil and I couldn't be happier! The smoking has all but disappeared, my prop comes out of the water clean. I'm convinced it's the oil! I'm getting ready to order another case! Thanks Amsoil...

Excellent oilI had a 200hp mercury efi engine that blew up when rod cap came off. Put a new powerhead on it, ran nothing but Amsoil HP in it. Loaned boat to a friend who trimmed it to high causing the engine to overheat. When it was torn down for repair the hone marks were still on the cylinder walls after 3 years.

Hp marine 2 cycleI have been an Amsoil and dealer years ago. Got out of it for financial reasons, and am now back! Always ran 100:1 in my dirtbikes, and have already noticed a significant change for the better in my 1990 Johnson 200 GT outboard. I disabled my BRO, so I run 50:1 permit with mid grade gasoline. The motor starts easier, less smoke, and zero carbon build up on plugs, even with fogging oil on spring start up. The previous owner ran sub-par syn blend and the difference in performance is night and day! Super happy to be back with the oil that started it all, and continues to be the best! Will be putting XL in my HD F150 this month! Thank you Amsoil for the blessing of fantastic oil I can depend on..... Item Reviewed: HP Marine Synthetic 2-Stroke Oil (HPM)

Great 2 stroke outboard oil.I run this in my 09 250 Yamaha HPDI bass boat. Could not be happier, clean plugs, engine runs flawless, very little smoke, and costs less than Yamalube. I also run in my old 25 hp Mercury tiller steer, runs and trolls at idle speeds great. Formerly ran this oil in my 150 hp Johnson for almost 10 years and had zero issues with the motor and a friend now owns the boat and still running great using same oil. 5 stars and costs same if not less than comparable synthetics.

Evinrude ETEC XD100 replacement oilI have been running HP marine in my Evinrude 300 on the lean oil setting for over two years. at least 300 hours of use. My dealer said the spark plugs look cleaner than most and almost did not need replacing after 300 hours. We opted to do so as we were going to put another 300 hours on it before the next service I burn 1/2 tp 3/4 of a gallon each day so XD 100 was adding up. I bought 3 cases of gallons when Amsoil offered free shipping. I was down aroind $30 per gallon where XD100 runs $44 to $48. at the local marina. Item Reviewed: HP Marine Synthetic 2-Stroke Oil (HPM)
