I gather that the decision has to do a lot with how much power you
have in your
Vanagon & how you use it. I've put a bit over 70000mi's on my 90Westy
since I acquired it
in Jun08 & the majority of those with a Canoe on the roof & some with
a RaftTrailer behind
& the last 40000 of which have been with an EJ25 below deck. I
generally try to drive @ or
slightly (5%) over the speed limit when terrain & winds allow so I
feel that I am asking the
tranny to do a bunch of work. I ran AmsOil 75w-90 for 37000mi, RedLine
75w-90 for 15000
& am now using Valvoline 75w-90 SynPower. The Valvo' is a GL5 & it
does have Sulfur in it
so before I switched to it I contacted Valvoline & told them what my
application was & was
assured that there would be no negative results from using it in my
VanagonTranny as the
Sulfur that they use is not damaging to YellowMetals. Since it was
many miles back, I don't
remember much about the AmsOil as far as Noise&Shifts go but the
Valvoline is very quite &
shifts flawlessly no matter what the temperature ( never yet below
10ºF ~ I missed a -7º test
here on 3Feb11 just a week before the change from R'L' to Valvo ).
With the RedLine the 1st
few shifts on a "cold" or "cool" start had to be done cautiously to
avoid a slight grind.
Bottom line is that Valvo' seems to be doing the job very nicely and
I have not, in the
past, let the price on a product have an influence on my decisions & I
don't adhere to the old
premise that you get what you pay for ( a Timex will give you pretty
much the same T'O'D' as
a Rolex ) ~ the fact that the Valvo is considerably cheaper than Ams
or R'L' & others is just
FrostingOnTheCake for me.
These are simply my experiences & I'm no expert so continue to do
your own research.
