synthetic oil in ZF transmissions???

Recommended Posts

malibu.c.c

some say no to sythetic other says yes...

the ZF manual has a listing of oils to use and some of them are sythetic...

others say to use base oil dextron III only

As no one seems to have a straight answer i would appreciate any help, as i am planning on changing oil in the next few days..

i dont see the big deal on sythetic and base oil .. ok one is made in a lab and more stable ..

and not to use sythetic in engines with less then 100 hours...( yet car manufacturers bring them out with sythetic oil in as OEM) ...

well to use or not to use sythetic if it meets Dextron III specifications..

???

and as for wearing out the transmission earlier if its synthertic that doesn make sense...

i have not found one article on the internet to say that a transmission has been damaged from use of sythetic oil..

any help appreciated and opinions appreciated.

thks

Use what it says, and change it every 50-100 hours/once a season and you will be fine. If you cant find Dexron III you can use IV with no problems.

Synthetic transmission fluid that meets the Dexron III or IV specification is perfectly acceptable to use in your ZF transmission.

Regarding your comment on synthetic engine oil. We use synthetic from the beginning on some of our engines as well. The LS3 Corvette and the LSA Spercharged engines get synthetic from the factory. These are new technology engines and are designed to use synthetic oil. The 5.7L engine block is far from new technology and the pistons, piston rings and honing of the cylinders was specified long before synthetic oil use became popular. Using synthetic in those engines may prevent the rings from seating in the cylinder walls because it lubricates too well and prevents the metal to metal contact with the cylinder walls that is required for break-in of the cylindrs.
