JPThing Owned by JP Mag...lol
« on: May 28, 2010, 03:35:50 PM »
For some reason JPThing decided to write a letter to JP magazine, pronouncing his ever expending knowledge of Zincy oils and thier benefits in flat tappet engines..especially the venerable Jeep 4.0l...and was again shot down...Sorry, but i almost choked when i  read this....

Quote
4.0L Oiling
Great job on the mag! I am writing to inform my fellow readers and jeepers about a potential engine-stopping issue: new oil formulations. A good friend of mine, James Vanderlinden, is an engine builder at D&W Performance, which is Calgary's (and possibly Canada's) finest and fastest performance engine building shop. He told me that over the past year or so he has seen several Jeep 4.0L inline-six engines come in with extensive damage and wear to the cam as a result of the newer oil formulations which contain little or no zinc.

According to Vanderlinden, this can spell disaster for flat tappet engines such as the Jeep inline-six. Newer engines and engines with roller cams are apparently immune to this. Vanderlinden's advice? Use diesel oil. The higher compression in diesel engines requires a more robust oil formulation and the zinc is still there, even in the newer formulations. Of course most diesel oil is 15w-40, which is a little thick for our needs, but in colder areas 10w-30 diesel oil as well as 5w-40 diesel oil can be found. Vanderlinden recommends Shell Rotella-T for older and flat tappet gasoline engines.

There are also oil additives available to overcome this shortcoming of modern oils, but they are pricey and tough to find. I hope this information helps keep more of these great old engines running strong! Long live the Jeep inline-six!

And the response...

This isn't the case anymore. The blanket statement "Rotella-T" or even diesel oil as a performance-engine alternative doesn't apply anymore because even they are going low ZDDP  (low zinc) to keep from killing the particulate filters in new diesels. Rotella-T and others are now CJ-4 spec. The old diesel oils with the good additives are CJ-I spec, which is being phased out.


Just cant stop beating that dead horse...lol ;D

I know,  I was being sarcastic.  Mixing up Canadian places is a Yank thing to do.

Funny thing is it took all of 3 seconds to google Alaska to find out it's AK.

In the zinc thread, did anyone notice the one guy defending the theory?  Read his stroker and juggy build threads on Pirate...no budget boosts or throttle body spacers there!   I'll listen to this guy and JPthing could have a point.

Yup, that's the one....just search 'go fast juggy' or something like that in jeep hardcore.
