It’s been reported that the 2021 Supra has excessive oil consumption issues. There is even a technical service bulletin (TSB): Engine oil level low, oil level at minimum that Toyota has issued to dealerships twice, on February 15, 2021, and on March 23, 2021.
The TSB states that customers may complain about high oil consumption. It also states that some Toyota Supra owners report illuminated dashboard warnings that say, “Oil level at minimum, add one quart.”
Online reports state that this oil consumption problem can cause engine failure in moving vehicles.
But Toyota doesn’t have a fix. Instead, the TSB is a tool for dealerships to gather information about the problem. Rather than recommending a diagnostic or repair solution, Toyota asks dealers to gather the following information from customer:
Then dealerships must create a technical assistance (TAS) case and contact TAS for instructions on how to proceed before trying to diagnose or repair vehicles.

Complaints to the National Highway Traffic Safety Administration (NHTSA) and in Toyota forums state, very simply, that their vehicles are using much too much oil. The Supra manual recommends the first oil change at 10,000 miles, but some owners are finding they need to top off with oil after they have traveled less than a third of this distance.
Here are some examples of comments and complaints.
A Supra owner from California states: “Oil consumption of 1qt at 2,800 miles and another one at 5,800 miles. Warning message prompted at each time to add a quart. Contacted dealer and tech. Advised same thing with no further assistance.”
An owner from Missouri states: (My) car is consuming a lot of oil in low mileage. Oil has been changed twice, once at 1,200 miles, again at 2,500 miles. Manual states oil change interval is 10,000 miles. Had an oil consumption warning at 7,xxx miles. Many other 2021 3.0 Supra owners are complaining of consumption issues.”
Both of these complaints are filed under Engine problems.
There are several different forums where Supra owners are complaining.
“I bought a 2021 Supra in April 202. It used the first quart of oil at 3,821 miles and the second quart only 2,181 miles later. I will not allow Toyota to do any engine work or engine replacement. I have filed all necessary complaints with Toyota. So far they have offered me an Extended Warranty. Toyota USA is going to contact me within 30 days.”
In response, another forum member with a 2021 3.0 premium Supra states: “Same issue here, almost 5000 miles and going for a second time to the dealer soon.”
In another forum, a Supra owner who got rid of the vehicle states: “Just returned mine because of oil consumption. I was going to keep both a new Z and a Supra, but alas that is not my fate. I look forward to getting a manual Z, but it doesn’t diminish the joy the Supra provided for a year. A (mostly) phenomenal car. Hated by internet warriors but loved by regular folks. I spent a lot of time in parking lots answering questions from giddy passersby who were awestruck. And track days were spectacular.
“A quart per 750-1000 miles was too much. My other B58 (M240i) did the same every 5-7.5k miles. I’ll enjoy the manual in what is likely to be my last gasser.”
