Going Synthetic?

[ottercreekfrog]

I realize this question has been asked many times, but here we go again. I am making the change to synthetic oil this weekend. Can I use Rotella T6 in my 2006 PSD? Towing 3700 pound boat in high temps. What vis should I use

Rotella T6 5W40 unless you live somewhere where the temp regularly goes over 100°F and stays there.

Synthetic oil is just oil that lasts longer.

You can switch to, from, and back to synthetic any time. If your in a pinch, you can mix dino and synthetic, as long as you change the oil at the "dino" interval and not "extended period" interal.

Lots of myths about synthetic. In the end, its just a longer lasting, more durable oil, and you just need to decide if it is what YOU need.

Take into consideration the underlying cause of injector stiction on the 6.0.
That is varnishes that are part of dino oil and is not found in synthetic oil formulations. Take apart any engine that has run solely dino oil and that brown stuff stuck to everything is what I am talking about. If that stuff gets stuck in the injector, your looking at stiction issues.
This is the reason why I use Rotella T6 full synthetic 5W40 oil. This issue rarely occurs in the 7.3, but does frequently occur in the 6.0

Hey, I'm with you.... I use Amsoil because I think it's the best.... but many are scared of synthetic. I'm just pointing out that its just oil... only better quality oil.

Listen to these guys. Synthetic is the only way to go.

Thanks for the input guys! I bought the truck new, only has 45k on it. No mods and planning on keeping it that way. Synthetic kept my Dodge V10 alive a long time, increased fuel economy and just seemed to run better. Just want my baddazz PSD to live a long happy life.

Don't expect any real MPG gains but the synthetic oil will keep it running smooth.

I run synthetics in everything I own. I wouldn't consider anything else for the 6.0. A bypass oil filter is a really good idea too. The primary full flow filter only filters to 20 microns.

I even have synthetic in my Crapsman Riding Mower!
