There are many combinations / recipes that work just fine if you cannot easily get the factory specified lubricants. Many people have their own concoctions that they have been using since the beginning of time with no problems. (myself included) And some folks on here think it is total heiresy if you don't use EXACTLY what the factory called for.
Keep in mind that in a pinch, ANYTHING beats the hell out of nothing at all! !
For the spindle, QC box, and apron gears I use 5W-20, synthetic if available.
For the ways, leadscrew, half nuts, and open gears (banjo gears) I use a mix of 75% 90W gear oil and 25%
+ STP.
I use these concoctions because they get the job done, I've been using them somewhere close to forever, and I can get the ingredients at the local auto parts store 1/2 mile away.
I'll probably get flamed for this post, but what the hay...............
Come on, JR, rip me a new one......................
