thinks its about time to do a tune-up on my car. ive been changing the oil regularly and recently just changed belts. i was going to change the spark plugs, trans fluid and diff fluid, as well as the oil and filter again. my question was what kinds of fluids and plugs i should get, and how many bottles of fluid. im using mobil 1 fully synthetic motor oil and filter. also is there anything else i should be changing up while im at it, thanks.

ALso a coolant flush, what type of coolant and how many gallons?

 

plugs check out https://g35driver.com/forums/engine-...ep-colder.html im assuming your N/A so regular is the one for you. trans/gear fluid everyone has their own opinions on what brand is best. i used to always use redline but recently changed them out to royal purple to try them out. no complaints.

as far as coolant, you can actually just use distilled water and a bottle of redline water wetter or the royal purple additive if you plan on keeping the car here in hawaii. as far as gallons, idk check your manual.
