Reining in an oil burning engine? (1 Viewer)

[gray rider]

I have no noticeable oil leaks. Currently burning a quart of 0w20 approximately every 1500 miles.
Can oil consumption be reduced by changing from 0w20 to 10w30?
Is the oil substitution ok in a 200 series engine?

Can a faulty PVC valve cause excessive oil burning?

Thanks.

How many miles? How do the sparkplugs look? All the same?

Sounds like a great question on the plugs....unfortunately the miles on the engine are a mystery. Here is the tread regarding that:

Salvage Motor Question

The 2014 200 that I recently bought may have a salvaged motor installed. (It has a heat tab installed on it) Anyone have insight regarding this topic? Thanks!

PCV valve has been a source of oil consumption multiple times on this board. Genuine Toyota part is less than $10 last time I checked, might as well throw one in. And I’d recommend using that over parts-store.

Also it’s plastic, don’t over-tighten the new one.

Beyond that, you can absolutely switch out to a thicker oil without harm to the engine, it is actually recommended in large parts of the world with this engine. Many of us run 5w-30 and even some 0w-30 with reports of quieter valve train.

Good info. I'm on it....

+1 on the pcv valve needing to be changed. As beaten to death before, the 3ur-fe is usually super easy on oil.

On the oil forum, people have had some luck after a couple runs of Valvoline restore and protect in reducing consumption. This hasn’t worked for everyone, but has worked for enough people imo to say give it a shot. Just be ready to change your filter early in the oil life cycle (assuming there’s a lot of carbon build up/sludge this stuff will be cleaning).

I’m not saying the valvoline will definitely cure your ills, but imo it couldn’t hurt. And it also comes in 5w30. HTH

@gasman: Is the "Oil Forum" Bob is the oil guy?

Valvoline Restore & Protect

I think it's just a guidance than some hard requirement of 4 oil changes. My car was burning a quart every 1K miles and it took just two VRP oil changes of 5K each and it seems to have completely stopped at 156K miles. I could probably switch to another oil at this point till I notice the oil...

That’s a good start. Just be ready for a deep dive into a lot of good info, but intermittent bullsh*t and voodoo.

VRP is good oil. IMHO it’s where I’d start (pcv first) to (hopefully) rein in your neglected engine burning oil.
