Scotty I bought a used 2013 Nissan Murano in 2019 It had 80,000 miles everything's running fine but I was considering on doing 100,000 mi tune up I actually have $125,000 mi on it now. 2 years ago I had new tires and brakes and the transmission fluid changed. The repair shop I normally go to once $1,500 to replace the plugs flush the radiator and replace the brake fluid do you think it's worth doing all that.
yeah it's not a bad idea to do those items, but $1500 is crazy. Try asking around for quotes.
flushing the coolant is a 125$ job, flushing the brakes is a 99$ dollar job, including labor and new fluid. and putting new spark plugs, im guessing you have a 4 cylinder engine, its 10$ a spark plug, if you buy spark plugs Make! Sure! you get the same kind that came with your car, but get a good japan brand. if you do it your self they sell the tools at walmart for like 10 bucks a piece, you need about 2 or 3 tools for the plugs. also be careful taking off the ignition coils to get the spark plugs, those bolts are old and crusty and you dont want to break them off, slow and strong turns taking them out. if you break them off in the block, youll need to reverse thread drill bit the broken bolt out if it breaks in the block, so the next bolt has snug new groves to go in, and go to lowes for 10 cents and by a little bit bigger bolt, and replace the ignition coil bolt. also dont put the plugs in super tight, just make sure they are tight, and a little snug. its a super simple job, like something a 11, year old could do. if you pay someone to do it its about 400 bucks.
also make sure you changing the transmission fluid every 50,000.00 miles. Change! the fluid, dont! flush the transmission fluid.
also i recommend, spraying the mass air flow sensor with mass air flow sensor spray. the mass air flow sensor is on the air intake tube. let dry for a hour after spraying it. you may get better mpg doing that.
