This is the best oil for an old two stroke cleanest plugs I’ve ever seen but the discount coupons expire too soon and the gimmicky free gifts are a joke

This is about half the price of the mercury optimax DFI oil, and Amsoil is always available, which can't be said for the merc product. I've placed 2 orders for this oil and both times, it arrived on my doorstep within 2 days. Can't be happier.

Been using amsoil for my 2 stroke 250 Yamaha HPDI and have had no issues.

All my 2 stroke friends love this oil Minimal carbon build up will idling minimal smoke

Bought this for an older 2 stroke outboard that I recently got, now the outboard hardly smokes and there isn’t the usual 2 stroke smell.

Outboard runs better and better every tank. May cost a little more but no question, it's worth it

I’ve never used any other oil in my outboard motors for years. This oil performs better than any other oil I’ve seen.

Started using this in my Mercury Optimax 200. Burns cleaner and doesn't gum up on the oil pickup screen like the recommended oils that Mercury pushes for its motors. Great piece of mind on a 20000 dollar outboard and I couldn't be happier!

Have been using HP Marine 2-Stroke for the past 3 years in my 2003 Mercury 225 Optimax now and what a difference! The motor run quieter and more smooth!! I love the reason that it is 100% full synthetic...I have been using full synthetic oil in all my vehicles and highly believe in it. Another reason is the price compared to Optimax oil...can't beat it and it exceeds all specs. Delivery was excellent and on time. With Amsoil being around for a long time with an excellent reputation how can anyone go wrong. Very satisfied with this product!!! Will continue to use Amsoil products for years to come...keep up the good work Amsoil!!

Only the best for my boat! I have used Amsoil since I bought my boat back in 1989. I tend to keep everything until it wears out and so far the 90 hp Johnson still has high compression in all 3 cylinders! Very lowe smoke on the lake.....!

Multiple payment authorization failures ordering online. The support staff, while friendly enough, are unable to do anything or help with the order in any way. You simply have to try reordering. This is painful and frustrating not knowing what failure occurred or why. On the second failure they had to contact the fraud department just to get my order filled and I still never received any feedback on what caused the failure. Terrible online presence. Stick with American products.

I have been running this in my 2006 optimax for over 100 hours. It has 800 hours on it and still runs strong. Also use it in my 1991 mercury 40hp and have no issues with that engine either.

Hands down the best marine oil on the market, performance is amazing.

Love the product. It works great with my Evinrude ETEC 200. Easy tompurchase and delivered quickly. My only gripe is I ordered a case, submitted the code for my free headlamp and I didn't get it with my delivery

This makes my two-stroke purr noticeable smooth running and clean burning oil

Great product but getting very pricey

Swicthed to amsoil 4 years ago couldn't be more pleased,top performance and very minimal smoke from my 1998 2-stoke.

Great product

I use to exclusively use XD100 in my Engine. Every once in a while, I would get a hint of that 2-Stroke smell, not often but never the less it would happen under certain conditions. After two seasons of using AMSOL, not once has it happened and I pay less.

I use this product exclusively on my 20 plus year old 2 stroke oil injected outboards and they run flawlessly. Little to no smoke and no unpleasant smell.
