TT Viper - Synthetic or Non-Synthetic Oil

[eabrillon1978]

About due to change my oil and currently using Amsoil 15w-40 synthetic.

I did a search, but there are some pretty old threads on the subject. There are some new oils on the market since then and also some different blends available now.

What do you recommend using? Is Synthetic preffered or Non-synthetic. What brand/weight are you currently using?


Any input appreciated.

I would say to stay with the synthetic, as it deals with the heat better than a conventional oil does.

Use a name brand full synthetic, no question. My Gen III specs 0W-40, Mobil 1 was factory fill. I am using this wt oil in my DD Mopars that spec'd 10w-30 to simplify things.
For non-Vipers that have cylinder deactivation, stick with the viscosity the manuals specify for proper operation.
