75k maintenance q's
 

Hello,
Asking forgiveness because I have a bit of a messy situation. I changed dealerships (horrid customer service issue) and they don't have any historic info on my vehicle so I'm sitting here googling maintenance items and trying to figure out what I have & have not had done on my vehicle in the past - I don't DIY anything and I'm not interested in doing so.

Car has 75k / 6 years old and dealership called to suggest:

1) rear differential oil change (had this done at 56k, so I think it's too early? // maintenance guide doesn't say how often?)

2) fuel injection service - have never done / use high quality fuel / drives fine; no rough idling.

3) brake flush - have never done.

Need all of these?

Go to the Scion owners portal or google "Scion FRS Warranty and Maintenance Guide" or "BRZ Warranty and Maintenence Guide". It has a break-out of the recommended services by interval. Any good dealer should be able to look up and know the regular maintenance items, so shame on them.

1) Diff and MT Oil, 30k miles if you're doing a lot of spirited driving. You can get away with 60k if you're just dailying the car. The manual actually doesn't have a recommendation on gear oil, they claim it should last lifetime of car. I personally like to do every 30k miles.

2. Fuel injectors aren't in the manual. However, fuel filter is called for at 75k miles.

3. Brake fluid flush is a good idea. Manual says every 30k miles

4. Spark plugs are called for at 60k miles. I think from experience, most people's plugs are pretty clean at the 60k mile interval. You can probably stretch to 90k to 100k if you only street the car.

5. Oil and tire rotation every 7500 miles, basically every time the car comes in.

1) Not necessary yet.
2) Never necessary. Pour some fuel injection cleaner in from time to time.
3) Maintenance manual recommends it. Don't recall the interval. Do it if you never have.

Of the things that were mentioned, the only item I would recommend is the brake fluid flush.

The dual injection system in these engines makes even the cleaner unnecessary. They just simply don't get that gummed up.

The old dealership should give you a printout/pdf of service records.

Have the new dealership change the brake fluid and, if you have more than 5,000 miles since the last oil change, engine oil.

1) I change my diff fluid with my MT fluid once a year
2) never done anything to my fuel injectors yet, just the italian tune-up once a week on weekends
3) did a brake fluid flush recently and it helped a little on the pedal feel. inspect the fluid, it should be clear/faint yellow .. mine was getting rough
