Oil burning Hybrid

"Alarming rate" does not tell us how much it is using. If you do not see blue smoke from the tail pipe, you may not have a problem. All engines from the last many years use oil between oil changes, and that is considered normal. To address the numerous complaints, all dip sticks are now labelled with "Min" and "Max" instead of "Add" and "Full". As long as the level remains above the "Min" mark, there is no need to add any oil.

It is a good idea to check the level after the oil is changed at a shop. Some speedy lube-type places could be tempted to just put in the least amount necessary to reach the minimum mark, to save a few dollars. The amount to refill during an oil change that is specified by the manufacturer will bring the level closer to the maximum level. If you do not find that, insist they add another half quart.

If you are using synthetic oil and it was not specified for your engine, it is likely the piston rings never seated properly. The oil consumption will take a lot longer to go down. Until then, the clue is you will find a lot of soot inside the tail pipe.

Not a surprise, Toyota has a couple TSBs out on these. You might want to contact a dealer. They will have you come in and perform an oil consumption test. (Basically they will top off the oil, record the mileage and tell you to return for them to check the oil and record the mileage) Just don't be shocked if they then tell you "It's Normal" They have increased the "normal oil consumption" for those to 1 quart in 1100 miles.

BUT if yours uses more that that, See what they suggest and contact Toyotas customer care center and get them involved. They have replaced engines before for this issue.
