I have been doing a lot of up keep and maintenance to my 91 80q over the last few months so I can keep the car a daily as its getting up there in mileage. The last time I changed the oil I used 10w-40 in it. I was wondering if you guys run a thicker oil in your higher mileage(200k+) 10v's. I have quite a bit of lifter tick with the engine warm and was wondering if this would help the motor out any. I already know its burning oil also. Not a huge amount but it still loses a little.
Next question is what the best tranny fluid to replace the stock is? Its something this car has been needing for a while so id love to get it done. Also the fill plug is on the ds of the transmission about halfway way up correct? I already have the 17mm tool for it so no worrys there.
Thanks guys for any help
