Driving on a remote highway in northern WI and low oil light illuminated, 1000 miles before oil change was due with less than 10k miles on the vehicle. Made it to a gas station and oil was a quart low. Vehicle burns over a quart every oil change interval, since this has been occurring since day 1 it is likely going to cause premature engine failure which would be a safety issue.

Experiencing a known excessive oil consumption issue. Low engine oil warning light came on and upon checking, oil was low. This occured at 4000 to 4200 miles. It occured again about 4000 miles later and again at a similar interval. I notified the dealer and scheduled a repair date but I am concerned of other possible damage that may have already occured due to this issue. An oxygen sensor needs to be replaced and is most likely due to the engine malfunction. The cause of the consumption is said to be damage to the valve seals on the exhaust side.

Purchased car in January 2020 and within a month/few thousand miles the low engine oil light came on. Almost two years later car continues to burn excessive oil triggering low engine oil light. Dealer doesn’t acknowledge an issue, Mazda still doesn’t have a repair. Owners required to pay for excess servicing until a repair is issued. This is a widespread problem impacting the engine.

After roughly 2,000 miles of driving, the low oil light comes on. The engine is burning oil. Mazda has issued a TSB on it, but they have taken no action to fix the issue. Right now they just top off the oil.

My Mazda 3 2.5T has been burning oil in excess. The car has a total of 24,000 miles and has been serviced 3 times. I have had to add oil in between every service. The oil has been completely burned off by 4,000-5,000 miles. I have noticed that other people have been posting about the same issues online. When talking to the dealership they state that they have noticed this issue with the 2.5T’s but offer no fix and seem to overfill the engine oil to try and compensate.

Engine is consuming excessive oil. Dealership states there is a TSB out but the fix is to keep topping the oil off. I would like an investigation to determine the root cause of the oil consumption on a new engine.
