Hi, I have a 2018 IS350 F-Sport RWD with 61,500 miles on it. I replaced spark plugs, Transmission fluid and brake fluid and I am doing Diff fluid soon as well as coolant. I was wondering if there is anything I should look for wear wise, I was thinking about upgrading the LCA bushings to RCF ones. But is there anything else I should inspect and replace that are common issues that people with higher mileage IS’ have had? Thank you

 

Clean the throttle body, clean maf, replace pcv, replace cabin filter, replace air intake filter, dump a can of Seafoam in the tank when you fill up.

 

Just keep up with regular maintenance on the car and use good quality oil.

For reference my 3IS has 176k on it.

 

Will do! Thank you

 

If I was intending to keep a car for a while then, apart from the usual maintenance items, I'd also apply some rustproofing to the underside, wheel wells, and sills (rocker panels to you folks). This could be a simply spray over with something like ACF-50 or Fluid Film, which would take less than an hour, up to applying a wax type treatment (I use Dynax products) to all the surfaces and cavities.

 

I’m actually going to be rust proofing my car, ordered everything I need to do wool wax. Ordered a few quarts of the material and a couple of their spray wands. I’m in it for the long run. I kept my Subarus from rusting with Fluid Film cans but I’m stepping it up to the next level.
