This is the appropriate oil for my Honda quad. Has always made the Honda engine last many many years! Price is the best I've found at Rocky Mountain ATV. The only oil I will ever use in all of my Honda products
Great oil for a great price I use it in mine and will continue to ......the manual calls for it and you can really depend on a honda they know there stuff
This is all I use in my Hondas from street riding to motocross racing and have never had any oil related issues. It compares in price to the other brands so why not buy Honda.
Great oil recommended for my new 2018 Honda Rubicon. Service manager at the dealership I purchased from told me I don’t have to use this oil to keep my warranty but I will use anyway. Honda oil and filter from Rocky Mountain are cheap, engines are not. Fast shipping to Tennessee.
Been using this oil since 2005 after I bought my first 4 stroke, (still miss my 2 stroke), some magazine did a test on a 450x after it had been thrashed for months and this oil stood up to the abuse, I've trashed mine also with very little wear to the piston/cam/rockers. Very pleased with the performance.
Meets all specs by Honda so as long as you remember to put it in your good! And for the price on a gallon it's not expensive as some of the other leading brands
Honda GN4 four stoke motor oil - recommend and Rocky Mountain ATV
This is a quality product and a good price. The entire transaction with Rocky Mountain ATV went very smoothly. The customer support provider was a little slow but was very helpful. I did not have part numbers so he had to try and find them. This product is exactly what is specified by Honda for maintenance on my new Honda Pioneer. I would definitely recommend this product as well as Rocky Mountain ATV for future use.
The only oil I will use on my road bike. This oil can easily go 8000 miles or once a year on oil change intervals. I average about 5k miles per year in variable conditions from traffic jams to 115mph
This seems to be really good oil, I've tried a few different brads of Atv oil in my Honda 420 rancher, and it seems to make my run smoother. I tried different brands including Valvoline ATV, Mobile 4T. With the Valvoline oil the bike was very noisy. I also use this oil in my Honda Crc 230.
Pro Honda oil is the only product I will use in my motorcycle. Now that I have found Rock mountain. That's where I will make all future purchases. Thank you ,
BEST ANSWER:Hi Brian. Can't answer your specific question. google that machine specifications and you'll find it. I do recommend that what ever weight they say it is make sure you say with the Honda Oil. I've had several 4 wheelers over the past years and have always used the Honda Oil. The Honda Oil has in it the right additives for the transmission. Regular SAE oil doesn't. Stay with the Honda Oil.

Most honda 4 strokes use 10w-40 in the engine side. Or you can use Rotella 15w-40 in both sides. But if you're using honda oil I recommend getting the honda transmission oil as well.
10w-40 is just fine and if the area is a really hot climate you can use 20w-50. Remember those crfs have two separate oils. One side for engine the other for clutch.
2007 Rubicon 500 is this the correct oil and how many quarts?

BEST ANSWER:You would have to check the owners manual for type of oil and what weight as for how much sometimes the side of the engine case says the amount of oil or refer to the owners manual again usually you can type in the question online and find answers pretty quick

BEST ANSWER:Yes, that is the service classification of the oil. Your manual may specify sg or better, so sj would be better. As they engineer new oils the service classification improves.
