Traditional or Synthetic? Which one ?

Whats inside right now?

How long ago did you go synthetic?

Poured it in and changed over, 123? or How?

Any differences....

just to amuse you.

Syn and I change my oil on schedule; 5000 miles.

Okay--synthetic vs. mineral??? Some questions:

Can you go "123" from mineral to synthetic? Is there anything special that needs to be done BEFORE you switch over to synthetic?

Can you do the same thing for the transmission--switch over right away from mineral to synthetic?

Does how you switch over depend on your engine/age/mileage of your truck??

 

[DaveBen]

Just switch over is all that is needed. If you want extended oil changes, you must get your oil analysised from some place like Blackstone Laboratories

Changed to Syn (Rotella-T) at 40K. Changed it again 1K later cuz of the Dino left in the engine (Purged).I have a Premo refiner so I change the 2 filters and add 2 qts every 5K. Change it all every 20K.

Been running dino since we took delivery in 02 but if the next Blackstone shows lead over the average I'll probably switch up to synthetic.

rotella dino, changed every 5k

how will synthetic oil lower your LEAD content ?

I use synthetic oils in all my trucks, it does get expensive, but well worth it. I noticed the switch in engine tone from conventional to synthetic in the 6.0 liter not as much in the others.

Royal Purple Synthetic in the engine, soon to be in diff's, and hopefully tranny, if they ever get it developed for the 5R110
