What's the best synthetic oil to use with the SVX ?

[sekler]

Hey guys !

first post here, eventhough I had read a bit on here before.

I got my '92 pearl white SVX back in october but I think it'd need an oil change. I already put 4000 km on it and don't know exactly the last time it was done (maybe another 5000 km ago).

What's the best synthetic oil to make sure the transmission and everything will last the longest ? Any better thing than the one suggested in the handbook ?

When the car is cold a bit, it doesn't run flawlessly, especially when going up steep roadswhile it runs good most of the time, it doesn't always shifts flawlessly (The transmission was rebuilt at around 150 000km and it's 206 000km right now).

While I'm fearing it could be the transmission, it's still been only 50 000km.

Anyone knows ?

thanks !

Simon
