Oil Change Interval

It’s been working for me.

 

So, because it works, makes it smart? Trucking is a business. Changing oil at a laughable 15k interval is a stupid business decision. Modern oils in modern engines are designed to last 75,000 miles. Doing it 5 times as frequent isn't doing anything but costing money and wasting resources that some people can't even find. Yes, engine oil supply is still tight.

 

I’ve done 45,000 miles so far this year, your telling me I shouldn’t of changed my oil at all?

i shoot for 10k but usually winds up being closer to 13-15k by the time I actually get to it…

oil and grease is cheap, and a write off

 

According to the engine manual on most trucks you would be correct once a year or $75,000 MI.

 

You're probably using non synthetic oil though. When he's talking 75k miles here it's probably because guy is using full synthetic.

 

I don't believe it says synthetic oil in the engine manual. I do however run synthetic, it might not even be necessary but it makes me feel good LOL and the price difference is only a few bucks a gallon

 

You don’t have a newer engine. So what he’s saying doesn’t apply.

 

How come this kind of "science" is okay for you, but not okay for them?

 

New engines don’t require synthetic for extended drains. Detroit and Paccar have bypass filtration. I’m not sure about Volvo or what the interval is on the X15 Cummins.

 

I use it because it has less ash to clog the systems.
