How many ounces of oil does your Prius use between oil changes?

My 2004 with 172K miles uses ~32 ounces (or 1 quart) per 5K miles.

 

Like yours, about 3 or 4 ounces every 5,000 miles. That was on the Gen II I sold recently. Had 79K on the clock when I parted with it. So far the new one doesn't seem to be using any.

3 pri, zero oil consumed.

 

I'm at about 300 ml per 5000 km (which equates to roughly 16 ounces per 5000 miles).

That's on my 2005 with 210000 km (130000 miles).

 

So little oil usage, anyone need to top off?

I change oil at 7,500 mile intervals (using full synthetic oil) so I'll add 1/2 quart at 5K miles to make sure the oil level is still well above the lower dimple when I change the oil.

 

'07 w/130k miles uses 16 ounces per 5k miles. This is down from nearly a quart in 5k miles after switching from dino 5-30 to Syntec 0-30 at 118k. ICE runs much smoother and quieter, especially at start-up. Got me convinced the Gen II Prius ICE IS worth a good synthetic. I keep the level at just below the upper dimple.

 

This is one of the few posts I've read where switching to synthetic at high mileage actually helping oil consumption. Good to know

Well, the German Castrol is known for being thick, so it's likely down to that. Mobil 1 0-40 would probably yield a similar result, speaking for my engine, anyway. I'd be spooked to try a typical 5-30 or 0-20 syn but I'm considering mixing a quart of Toy 0-20 into my next change just for giggles.

How much quieter and smoother the thing runs is the bigger plus, imo. Don't know if lighter syns would do the same or not. I'm scared to play around too much and end up with engine clatter and real consumption!

 

Yea, but it's completely wrong. I've been using both dino and synthetic oil for 30 years and switching too synthetic in high mileage ALWAYS increases oil consumption dramatically in cars that consume some oil. Switching to conventional oil from synthetic (equal weights) always decreases consumption dramatically.

 

I'm at 170K miles. With 5w30, we consume a quart every 5K miles. Using 10w30 decreases that to about 8 ounces.

 

I'm going to try a change with pennzoil platinum 5w30 next. My 08 has started burning oil ever since I tried mobil 1 0W20 once. I'm hoping the pennzoil will clean out the motor a bit and bring my car back to little oil consumption.

Just read an article published by Art's Automotive regarding oil consumption. They still believe in the 3000 mile oil change. Not so much that the oil is no longer good, but it's a good way to not run out of oil. The recommendations from Toyota having a 10,000 OCI is just crazy, most people will run out of oil before that OCI comes around.

They state the average car still uses about 1qt every 1500 miles after the car reaches 60k miles. So a higher mileage Prius can easily burn 2qts before 5000 miles (Gen2 OCI) and engine damage can already occur.

 

I feel like I'm looking in the mirror! Exactly the same mileage, exactly the same consumption, and exactly the same habit of frequently topping off to keep the level close to (but usually just under) the top dimple.

 

Wow, 4 times more consumption on 5W30 compared with 10W30. I have used higher viscosity oils in the past (with older cars) to moderate oil consumption, but I still wouldn't have expected that bigger difference.

 

I have a 2011 Prius Two. Mine uses zero between 10,000 mile oil changes. Has 47,000 miles on it.

 

My wife's has 150K on it and doesn't use a drop.

 

2007 195098k uses 3-3 1/2 quarts between oil changes.. and getting worse. oil changes are at 5000 miles.
