The 12 month / 10,000 mile service was due on my 2024 Prius Prime. The car has @8400 miles and I have done 2 oil changes myself. I did the initial change at about 1500 miles and the second at 5000 miles. I have decided to change the oil at 5000 miles / 6 months. I use the Toyota oil, filter and drain plug gasket. Total cost $35 USD. I needed to get the rear door lock recall on my car so I scheduled that and the maintenance items covered under Toyota Care that is free of charge for the initial 2 years. The dealer did the recall, oil change and tire rotation. Less than 2 hours and I was pleased with the service and courteous employees. After any work is accomplished on my vehicles, I always do my own quality check. Confirmed the tire lugs nuts were torqued to 76 ft/lbs per the OM. I did note the work order had the torque listed at 80 ft/lbs. Not an issue. I checked the oil which was cold, i.e., I did not use the engine on the trip home. I found the oil level about 1 inch above the upper dot on the dip stick. I pulled and checked multiple times. I siphoned out about 0.5 qt of oil to bring the oil level slightly below the upper dot with the oil cold. I note on the work order that with the drain and refill and filter change, the tech added 4.4 qts. The OM on page 602 states 4.1 qts for drain and refill with filter. I have found 4 qts works best as the oil level with engine cold is slightly below the upper dot. Why the dealer WO states 4.4 qts makes no sense as this resulted in an overfill with the engine oil COLD. Toyota advises to check the oil level when hot after waiting 5 minutes. Whatever. I have always checked my vehicle oil levels with the engine cold since the dip stick reading can be hard to determine since oil splashes up the dipstick tube and complicates an accurate reading PLUS I want to know I have oil BEFORE starting not after running the engine. It just never ends....... Cheers
Just remember...Dealership oil changes are almost always done by non licensed "personnel" in the express lane...even if other work is being performed by licensed Mechanics. It's good of you to check the work. Most folks can't or won't.
The tech mistakenly used the info for a regular Prius, not a Prime. Probably didn't realize there was a difference. The Prime needs 4.1qts, but the Prius HEV needs 4.4qts.
