Cant go wrong with this oil.
This is great oil at a decent price. I use this oil in my 2024 Yamaha Raptor 700R and my 2023 Suzuki King Quad 750. Never a issue. Suzuki has 3200 miles on it already and It runs flawless. Never had any issues with this Maxima oil. This oil is a great wet clutch oil, both my atvs have wet clutches and both operate perfect. I have ran this oil in many dirt bikes and atvs with wet clutches and never a clutch issue or motor issue. I will always trust in Maxima Syn Blend 10w40.

Quality oil for Polaris Ranger
Excellent! The local Phoenix .. UTV Pro Shop recommends this brand and type for my Polaris Ranger. Says the racer guys use it all the time. Reports the oil stays cleaner and doesn't evaporate & burn off like 0-40 Polaris oil. Thus safer to use on long runs since oil stays in the crank case. Confirmed in my Ranger. Oils looks clean and still full after several tanks of fuel. Not sure, but seems Polaris changed their specs about very low viscosity oil. Suggest you check. I think they now begin with 10 weight ... which this is. Considering it's 115 outside, this oil seems to hold up well so far. Even put it in my standby Champion portable generator. AND since buying a gallon container on Amazon ... the price is about $3 per quart LESS than the Pro Shop.

I read about this as a recommended oil on one of the ATV/Dirt bike forums so I figured i'd give it a try. I like to change my oil on my bike after every 2nd ride. I've gotten 3 oil changes out of the jug so far and I've had zero complaints. The oil holds up nicely when I put in those long hours on the bike. There is no clutch slipping or anything weird going on. and it comes at a great price. I will definitely be re ordering this oil.

Great semi-synth motorcycle oil.
Good motorcycle motor oil. Seems to have quieted my engine overall, and because its semi-synth you don't have to worry about the gaskets shrinking and causing leaks like you do with full synth in older bikes. Plus, since its a gallon, no fussing with multiple bottles for each oil change and there is more than enough to fill the crankcase and new filter, and even top off once you get up and running. I'll buy this again for my next change.
