It is UP TO 35K and is not Gauranteed in every vehicle... Besides that, it is confusing the issue even more on a MOtorcycle site.
mxrider i looked at the link you had then thought about looking into amsoil here is what they say about it -Amsoil guarantees their Signature Series Oil in normal service – up to 35,000 miles or one year, whichever comes first in vehicles that are currently under factory warranty as well as vehicles that are no longer under warranty. would u let ur car go 35k miles on one oil change ....no because the manual says 3k or 5k i dont believe much that comes out of oil companies mouths who i do believe is the engineers that make my engine who say 8k for oil changes
So, we can use the same analogy for Fram filters then? They are on the shelf so they won't hurt the engine . I know of engines where the cardboard came apart in the Fram and clogged the oil passages thereby starving the engine for oil and seizing it. I have also seen Fram filters with holes in the media almost the diameter of a pencil. Another just recently where the media was not crimped properly allowing unfiltered oil to flow through the engine.
Not that I am disagreeing with you about RP even though it is a Crap oil, just the analogy used.
RP oil won't hurt the motor....if it has hurt a motor.....it wouldn't be on the shelves...everyone has their favorite oil and they will try to persuade you to use their brand....any kind of synthetic oil for motorcycles is good to use...
Honda or Honda Dealer ? Big difference. Also, if it was Mother Honda, they should specify that those are not the Severe Service limits. Severe Service limits, which should be followed in all situations, according to the API, is 50% of what is listed.
i called honda today and they told me to follow what the owners manual said 8k or 12 months on oil changes
and being a drag guy you should already know all the bullshit oil companys spew and should understand that when you spend the 12 bucks on the royal purple instead of the 5 on castrol gtx, your just paying for the color additives and the marketing prices
i have yet to see any real hard evidence that shows that any kind of synthetic or "fancy" oil is any better then the regular dino ****
my buddy and my engine builder/tuner whos been working in the buisness for over 30 years even told me hes seen no differences in wear patterns
and he can spot an engine thats run with and without premix
Paying for color additives and marketing ? Although RP is not a great oil, there is a lot more to it than color and marketing. The Ester base stocks are quite expensive.
No evidence ? There are reports abounding about synthetic oils and their use. Corvette, Viper, Prowler, Porsche, BMW, Mercedes and other OEMS recommend Synthetic oils and in fact, some require synthetic oil to maintain the warranty or an extremely shortened drain interval must be used.
Warranties on engines, transmissions and rear diffs have been extended due to synthetic oils.
353,000 miles may not be a lot, but let's see you do that on 25,000-35,000 mile drain intervals. My work van has. Over 220,000 on the EAO 4D tranny and still shifting solid as a rock even after towing heavy loads in OD. Oh crap, I forgot, I was running a Non-recommended fluid.. LOL
How about a Chevy work van with over 920,000 miles on it ? All on 35,000 drain intervals..
Let's see you do that on a petroleum.
