I have a '74 914 and the transmission is a little leaky and need to change the fluid, the book says to use straight 90w oil but I am having a really tough time finding it so I was wondering if there was a newer substitute that I could use. This is my first 914 and I am struggling a little bit and could use some help thanks

Regarding heat... In another thread elsewhere it was mentioned (I think by Jake Raby) about the percentage of power loss via a 901 transmission. If I remember correctly it was above 20% which is high, but he had the dyno numbers to prove it. My point is that you have to remember that all of that energy is being converted into heat and noise with most probably being heat. I wouldn't be surprised if the 915 has similar friction losses and ultimate potential for heat generation. And the more power you put in, the hotter is will get. At some point cooling is needed.
Oil is and will always be a religious discussion. And while there is plenty of "opinion" here, I think there is also plenty of "fact" as well. All fluids in a car live a tough life. Some worse than others. At a minimum the factory put in a service schedule for a reason and I suspect the primary reason was to not just sell you more oil at service visits. And about the best empirical data we have is that regular old "dino" or "mineral" oil has worked well for decades in these transmissions. Otherwise, there is no need (for me) to rehash what has already been said! (IMG:style_emoticons/default/biggrin.gif) Richard |
