It's my understanding that the ZDDP was removed from car oils because it was bad for Cat-converters.
Might not want to use it if your vehicle is cat equipped...

I run Rotella in the backhoe, & lawnmower, & I WUZ running it in the pickup, cuz I Fergot about the Cataclysmic Perverter,, but Ill stop doin that,,

My buddy who is a mechanic recommended this for my f150 which holds 6 quarts.  5 quarts of good oil (mobil super) and 1 quart Rotella T.  He said if you want to run traditional oil use that but, if you if you want to switch to synthetic wait till 30k.  Then use mobil 1.  He has 500k on his original engine.  For every other vehicle / engine he said use rotella T.

Yeah.....I'm with you Dave. I figger if my oil can harm my "spent fuel" emissions via my cat converter, I gots a problem with oil in my fuel, yes?
Anyway I put some in, drove it till warm, and it seemed fine. I have full instrumentation on my dash, not idiot lights, but real gauges and the oil pressure is riding at optimal.
I'll let you know next week, as I will be driving to work again as the savage rest due to cold weather, its snowing as I type......  

I ran T-6 in an Acura Legend and a 2.5 TL all the time -- and I did  have to replace an oxygen sensor on one or the other about every 4th-5th year or so.   Can't say much about that being strictly due to the oil, but I suspect it had something to do with it.

Did the T-6 oil help with engine life?   Mebbe, I traded them in on Nissan Cubes last couple of years to get a more creaky old person friendly car.   Both engines were solid right up to the end, with the Legend being right at 300,000 miles on the ODO.

In the long life engine rally world, I wouldn't even have qualified.   Heck, some truckers have run more miles on one single T-6 oil change than I ever reached on my oldest Accura's engine in total.

Don't that put things in perspective for you, huh?




===========


T-6 doesn't burn up all the way when it goes past the rings, BTW.   There is an oily liquid that builds up in the muffler that would drip out of the little water purge holes that Acura put in the Legend's stainless steel exhaust system.   This is in line with what Klotz synthetic two stroke oil used to do (how it worked "better" actually).

Your cat converter beads would get oil totally soaked/coated driving around town for years then when you hit the interstate and got it all nice and hot the beads would ignite and then burn it all off suddenly.   Took 5-7 minutes to burn the T-6 off completely and it really smoked bad while it was a going about doing it.

Skeeter fogger time  !!!    People blowing the horn at you and rollin' the windows down to tell you your car was on fire, etc .....   My wife used to get all embarrassed and mad at me.

Is that a 300/6 banger?
