Hi,
I saw two automatic transmission fluids in the shop: AQM and AQF. I presume some cars need one and some cars the other, but why; what is the difference between them?
Actually I have a manual and was looking to buy some fluid to use as a fuel additive because it has been recommended many times here before, that redex and others use atf as their main ingredient. For use as injector cleaner fuel additive, can I use either fluid?
TIA
