Thanks for the info. I CAN recommend Honda HP4S motor oil. I've used it now for two oil changes in my 2016 Honda Rancher and I'm very impressed. I now have 73 hours and 680 miles on this oil change and the oil still looks as clean as the day I put it in, and I haven't had to add any either. I will change it soon, but I've noticed with HP4S the DCT transmission feels slicker and the engine sounds less labored in below-freezing start ups.
Does that oil cost much, the Mobil 1 4T is $9.80 or so a qt at walmart and was wondering if it will work in any engine like say 300 fourtrax? I know what works VERY well for me but I was curious.
EDIT: I looked online and found that oil was MORE EXPENSIVE than lthe oil I'm running. On Amazon for 1 Qt its like 16.00. And read online reviews Bobs the oil guy I think, but I know they said its really nothing special just over priced. I see why Rusler doesn't recommend Valvoline atv oil. I know Honda contracts them out for their GN4 oil and it's the worst stuff there is, look for reviews and you will see.
Here is the review on the GN4 oil
Honda oil is made of the cheapest stuff on earth...
ByCharles Tateon December 24, 2014
Just how bad is brand specific oil? Well for Honda owners this oil is the worst, and perspective buyers should steer clear from it if they enjoy their engine.
I ride a 2001 CBR600 F4i, and I noticed after about 1500 miles on this cheap oil I got a slow leak. I'm not blaming the oil as that could be due to many different factors, but this is a super clean bike, with low mileage(7900) and on the previous oil it never leaked. While searching around the web I found some startling information regarding this "Pro" oil and I just had to rewrite my review based on what I found.
Pro Honda GN4 is made from the cheapest base stocks possible. I can't link the testing but if you look around you can find that this oil was tested against other budget motorcycle oils and against mid to high end motorcycle oils. The testing results revealed that this Pro GN4 oil was the absolute worst performer on about 10 different tests available across 15 different brands of oil. Long story short if you want long life out of your motorcycle you should simply look elsewhere. I'm not saying it won't work, but if you care about the machine you sit on and trust your life with you should do yourself a favor and upgrade to something else for the next oil change.
All of the tests revealed GN4 to be the lowest quality oil period. Honda contracts oil from whoever's willing to sell it to them the cheapest and meet the absolute minimum spec's possible for our bikes. They buy the lowest grade oil for the cheapest price, and throw their name on it and price it out as if it's quality oil you can count on, but in reality it's the riskiest oil you can run in your machine. Being the lowest performer in all tests simply means increase ware, reduced engine life, and more repairs if not replacement.
To add insult to injury I rode about 240 miles on the bike today to meet up with a few buddies. One of them had a CBR1000 with 190,000 miles on it going strong! Now that is why I purchased a Honda! The kicker of course is that he never ran Honda branded oil and he purchased the bike brand new. He's used a variety of different oils, after the initial Honda break in period and recommended a few big name brands.
After some talking he recommended anything that meets the bikes requirement that was sold by anyone other than Honda. Some brands mentioned were Mobil 1, Red Line, and Royal Purple. After looking around I found Red Line sells a 1 Gallon bottle for $60 shipped and decided it was worth it to at least try something high end. I intend to ride from NY to Panama Canal soon and after I put some miles on the Red Line fluid I'll leave a review there as well. It's Red Line 42405. It's a 4,000+ mile trip, and although I like to change my bike around 2,000 miles I might use the Redline for the entire ride there. Ride report coming soon!
