Cummins X-15 500hp, full synthetic?

First question would be how often do you change ur oil? Full synthetic oil isn't cheap. Unless u are doing the extended drains I wouldn't run it. Maybe go with a semi synthetic.

 

I only run full syn, regardless of age.

 

I always ran T6 and changed it at 20K miles…..

But I wasn’t paying $100 a gallon for it.

 

A hundred a gallon.

I want to be your oil salesman.

Heck I'll only charge you half that.


Did you maybe mean a hundred a pail?

 

On my 2014 ISX 15(2016 recon long block) I use a local oil distributor house synthetic blend that cost me $12.00 a gallon, was paying about $8.00 a few years ago but everything has gone up. I change it about 10-12,000 miles. This last oil changed I went 13,000. Several on here swear with those long interval changes. But I have a peace of mind doing the way I service mine.

 

What type of warranty emissions work was already needed on your 2021?

 

I actually do mine by time, not miles, some of my trucks don't run a lot of miles, but pile up the hours.
Six weeks works.

 

I’ve never gone by hours, just curious, at how many hours do you service yours and what does that equal to in mile ? I run locally and I don’t let the truck idle much unless it’s extremely hot and/or I’m trying to cool off before I go back to securing my load etc……..
