I hit the 5k mark since I changed over to the AMSOIL 15w-40 HD Marine/Diesel oil with the AMSOIL ea oil filter. Just wondering when you guys are changing your oil filter but letting your oil change interval go further??

I dont drive with a heavy foot and dont tow very often...when I do its only my 17ft enclosed trailer that I haul 2-3 quads in to MX races. I was thinking go to 10k and then order an oil analysis kit, more oil, and another oil filter to change out soon as I get it along with doing an oil analysis. What does everyone think?

Anyone actually letting their filters go the 20k or 25k that AMSOIL "rates" these oil filters at? I'm kinda wary about letting the filter go that far...

 

I change it every 10k

 

Just my $0.02.

I'll run the AMSoil 15w40 oil @ the 20k change and will change the oil and filter at 25K. I'll draw a sample and get it analized, if the analysis says I can extend to say 7500, I will but always change filter with oil. I see it as false economy to change one and not the other.

Cheers

 

Ramble Bee...you are meaning just the oil filter right? What is your intervals on the oil??

Thanks for the input fellas!!

 

Just a reminder RedRacer:

Cummins does not recommend you go 20k on any oil regardless of the brand. 15000 mile normal interval, 7500 mile for towing and severe service.
