Just got serviced and turned a lot of things down

Personally, it's just a money maker for the dealership.

Modern fuel has ethanol in it. Sometimes 10%, sometimes 15% or more. Ethanol will absorb moisture, if it's exposed to it. There's always a chance that if left sitting long enough (years) that ethanol may absorb enough moisture to cause a bit of water to settle at the bottom of your gas tank. But, it's hard for ethanol to absorb moisture if it's not exposed to air, right? Modern fuel tanks don't exactly have ventilation fans blowing fresh air into the tank.....
If you drive your car like a normal person, you consume the fuel plenty fast to have nothing to worry about with moisture. If you have any concerns, there are a variety of "ethanol treatment" products available at just about any store, including walmart, that you can buy for about 10 bucks and add it to the fuel tank yourself. It's just chemicals that absorb any water that may have formed in the tank. I believe most also include chemicals for "fuel system cleaning" like injector deposits that may build up. All the dealership is going to do, is pour in a $10 bottle of treatment and charge you $75.

 

Short answer “nope”. Take a look at your owners manual and you will see Toyota telling you not to use fuel additives (I’m sure, tho’, there is a conspiracy theory someone here believes, that says Toyota is up to something giving that advice). If you only use TopTier gasoline, you won’t need the additives or the injector cleaner either.

 

just follow the maintenance schedule and change the tranny fluid

 

The only thing I would add is checking the battery filter, and cleaning it (which is too simple to do to pay someone else to do it).

 

Dang they must be hurting for money....none of that is needed. I agree with Pulse07 about only filling up with Top Tier gasoline...you won't have to worry about cleaning out fuel injectors. (There's websites to find one near you.)
Have you checked the engine air filter? I've found the smaller ones in our Prius needs replacing more often so mine usually get replaced every 8-12 months, depending on how dirty they look.

 

Ethanol treatment: No. The engine can take up to 10% ethanol fuel mix. Even if you park for a long time (weeks to months), you should just use a bottle of fuel stabilizer.

Fuel Injection cleaner: No. If you had to, just run a tank of Techron or buy an additive like Berryman's or Techron.

Wheel alignment: No. Unless you hit something too hard and fast, did work on the suspension, have uneven tire wire, or no longer track straight. I never did alignments on the OEM tires and still got some 45k miles out of those.

Battery filter: No. Unless your car is perpetually dirty or you have long haired pets, this filter would last a long time. When I changed it, it probably had 95% life left. I keep my car's interior clean and have no pets BTW. Plus it can be done in under 5 minutes.

Fuel injection cleaner additive is a hot topic issue. Some people say if you use top fuels only (Chevron, Shell, Costco, etc.), you won't need fuel injection cleaner ever. I disagree. Fuel combustion generates a lot of byproducts and will inevitably get dirty. My take on this issue is thus: It's much easier to keep a brand new engine clean than it is to clean an engine that has been dirty after years and years of use. I use Berryman's twice a year.

 

These are good data points from this dealership. Dealerships may run like typical auto repair shops and do stuff like this. If your car is still running, and they recommend various things, do the homework and decide whether it’s worth it. Never agree on the spot and be blindsided. Good job on not being tempted. Definitely do battery filter yourself. Wheel alignments are good to do every couple years for mileage efficiency, depending on how bad condition they are…but best to shop around.
