Curses! they overfilled my Gen III too!

[Gadgetdad]

I had hoped that my dealer wouldn't screw up a simple oil change on the Gen III by overfilling......I was wrong.

I hoped I could leave the more complicated oil change task to the dealer and was assured they would use the Mobil One Synthetic. I was a bit annoyed that I was charged for 5 Quarts when I knew that only 4.1 was needed (yes 4.4 if oil filter is changed), and overall the price was fair. But I had a lingering worry that I just checked. Yes... too much oil!

A good 1/2 inch over the top fill mark on the dipstick was the read. I couldn't believe it and wiped the stick several times to get an accurate read. I've driven about 200 miles since the change last week.

Should I have the dealer drain the excess or replace all the oil due to possible foaming? Is the foaming of overfilled oil even a problem on Gen III?

Next time, if I don't do it myself, I will ask they only use 4 quarts and let me top it off if needed. Certainly I will check the oil before I leave the service area.

This is irritating, Toyota, if your listening, please train your dealers! This continuing problem with dealers lessens their and your credibility.

At least they put oil in yours. I heard a horror story of them not putting any in. The girl I know of course didn't check it before she drove off the lot. The rest you can figure out. After many problems having dealers change my oil I do it myself all the time. I have not let a dealer change my oil in over six years. It's sad they screw up the easiest tasks. But when I see the people they hire to work there I understand.

LUBRICATION SYSTEM
ON-VEHICLE INSPECTION
1. CHECK ENGINE OIL LEVEL

NOTICE:
Do not fill with engine oil to above the full level mark.

I'm thinking about scanning the page and putting it and the cover page on my web site. Ask to speak with the service manager.

Ok, I have a real newb question to which the search turns up nothing...the oil is so clear and the stick fits so tightly that it has oil on the sides of the stick. It *looks* like the oil fills the stick at the top dot, but how can I tell if it's overfilled if I can't see the "fill line" on the stick?! Or is that my answer...if it's on the sides, then it's overfilled?

They charged me for 5 qts, too - as well as charging nearly double the posted (asterisked - Some models slightly higher - my emphasis) $43.90+tax for the 5K service. I paid 59.74 - $28.95 labor + $35.36 parts + -$9 coupons + 4.43 tax. I 'discussed' it with the cashier and left a scathing review but haven't heard from anyone yet. If they also overfilled, I'm writing the service manager posthaste rather than waiting a few more days.

I think you got an ok price, mine was $77. The synthetic oil was charged by the quart at full retail price. I changed my oil in my Gen II Touring after an overfilling episode before, but I thought the task would be better handled (due to the mess and acess issues) by the dealer's service department. I'll speak to the service manager and get a written statement in case I have a problem develop down the line.

Check the oil level on the dipstick several times to get a good read. Wipe the oil off the stick between checks, and make sure the dipstick is pressed all the way down into the hole before pulling it out. Hold level and look for the leading edge of the oil on the broad side of the dipstick. It may take a couple of tries to see it. I hope you already know to check oil with engine off!

Thanks :-) Yes, I do know to check with the engine off. I waited 2-3 hours after I got home for it to cool, but I'll check again in the AM to see if I can see any better. At $6/qt, I will def. be asking them for the extra 1/2 qt next time!

I would probably have been OK with the price if they didn't have the $43.90 plastered all over the place - and given me a card with it on when I went to the service desk BEFORE I bought the car. The 10K service price worries me if that doubles!

Me thinks will do the 1st service at 5k at the dealer. Subsequent ones will just buy my choice oil and take it to the Sears auto center where I didn't have any trouble servicing my old non-hybrid. I'd do it myself, but for two reasons:
1. I live in an apartment community and park the car in an open lot. There may be objections for fear of oil spills.
2. Accessibility under the car. I considered both the ramps and stand options. I am not comfortable with the thought of either in an open lot.

Just had mine done last Thurs - this post prompted me to check. About 1/8" (2-3mm?) below the full mark. Avondale Toyota must have been schooled in the past on this

"Certified" Toyota technicians have overfilled my 2006 Prius several times. They will never touch my car again...

I change my own oil because I can let the old oil drain out longer 20-minutes before adding new oil. You will need a ramp in order to get the plastic flap down far enough to remove the drain bolt and filter cap, which was real easy. Did I hear that Toyota moved oil changes to 10,000 miles or was it 7,500. I like the 7,500 oil change best in all my other cars. I use Mobile 1 across the fleet and 0W20 in the Prius. That is the latest and greatest oil! 5W30 is going to 0W30. Way to go Mobile 1!!
