I have a 2001 gmc 2500HD duramax with 375,000 km, all i ever used was regular 15w40, but im thinking on switching over to synthetic, is it a good idea to do this, this late? or will i hurt the engine doing it this late? any suggestions?

I am a synthetic fan, but why mess with your proven formula..."if it ain't broke, don't fix it!" just my 2 cents, maybe someone else here has a good reason for the switch. Luke

Is something about the truck's performance or "feel" different or changed, making you want to try something?

I likewise wouldn't change a thing if it's gone that far without many problems. Really curious to know how much oil it's burning. How many miles do you get before needing to add a quart??

I guess it is up to you... Maybe do an oil analysis and see how the oil you are using is performing near the end of its change interval. I guess you can extend the change interval with pure synthetic, But I am a believer in the "don't fix what isn't broke" theory. I really don't see the need for synthetic and the additional cost unless you are trying to extend your service interval.

My truck doesnt burn any oil, and i change it every 5000 km, but after reading the replys i dont think im going to change, just thought it might prolong the engines life, but the truck is working fine now, so thanks for the replys!

Hey,

I run synthetic in the cold months ( October untill April. ) and Dino the rest of the year on 5000km intervals. I love the advantages synthetic offers for cold starting, but don't think I would run it the rest of the year.

Like WB said, I think it will depend on where you are in the world. Cold temps, synthetic is better and will make the truck run better, IMO.. I say if you have had no issues running dino all the time then why change now? Reasoning?

For sub zero I'd consider synthetic but other wise unless you just want to spend some money or have bragging rights I recommed dino. I'm usin a blend right now but as soon as my stock is gone I'm switching to a good dino.
