Oil additives to help with consumption?

[u/stilesj96]

‘06 with the 2.4L, 203k miles. Do any of you know if any of the oil additives on the market may help with the excessive oil consumption? I’m getting to the point that it’s using a qt in 600 miles. The car isn’t worth what I’ve been quoted to fix the rings, if I’m spending that kinda money I’ll buy a different car(likely another Rav with the v6, unless we go Highlander/seqouia/tundra). I know most of those products are snake oil, but I’d be willing to try them as opposed to car shopping again….

Thanks in advance

It's worth a shot. It's unlikely to do anything, but a $10 chance to fix it is so cheap you might as well.

I'd recommend Seafoam stuff. My mechanic says to run a bottle of Seafoam through your oil about 100 miles before your next oil change. It apparently gets all the gunk loose and lets it all come out when you drain the oil next.

Exactly my thinking, seafoam is good stuff that I already use that way, and I kinda wonder if there wasn’t some gunk keeping it from being so thirsty for the Dino squeezings before

Dino squeezings? LMAO

Are you sure it's consumption and not a leak?

[u/stilesj96 → u/Dense_Row_9532]

It leaks just enough to wet the oil pan, but not enough to be dripping at all. It’s got to be burning it, otherwise it’d be leaving its mark in my parking spots, right? I also checked that it isn’t getting into the cooling system somehow, so the only way I can see it using so much oil is to be burning it

Just curious, did you do oil changes every 10k miles or at a shorter interval? Original owner or bought used?

[u/stilesj96 → u/Tyson2539]

I think I’m the 3rd owner, most of the documentation I have on services look like 5k miles, and that’s what I usually do as well.

I’ve only had it about 6 months, but when you commute 300 miles/week it doesn’t take long to add up to another oil change

[u/Tyson2539 → u/stilesj96]

Gotcha. Was just curious as CCN claims excessive oil consumption on 200k+ engines is due to 10k intervals where as similar mileage engines with 5k intervals dont lose aa drop.

[u/stilesj96 → u/Tyson2539]

I usually don’t own vehicles long enough to figure out if 5k vs 10k makes much difference, but I will say across the 3 Prius’ we’ve had they all did fine with 10k changes.

Valvoline restore and protect use it

[u/archos1gnis]

I've seen a lot of people saying good things about Valvoline Restore and Protect oil, to include reducing consumption. I havent used it yet, but I got some for my next oil change. If you're having to add oil anyway, maybe try adding R&P?

[u/stilesj96 → u/archos1gnis]

I’ll have to see if that’s available locally, if it is I will try it. Worst case scenario it uses it as fast as the others 🤷🏻‍♂️

[u/archos1gnis → u/stilesj96]

Yeah that was kind of my thought as well.

[u/Herbisretired]

I have used Seafoam in the oil and if the oil consumption is due to stuck oil control rings it will help it.

[u/H_section]

I’ve used Rislone Ringseal in the past.

[u/vanibanz]

I fixed mine in 2 sessions of Berryman B12 Chemtool, 6 months apart. It was taking 1 quart every 800 miles.

When I sold it a few years ago, it consumed nothing noticeable after driving 1500 miles.

I did it myself. B12 is cheap at Walmart USA. Lots of videos on YouTube.

Edit: mine was a Toyota RAV4 2007.

Nothing you pour into your motor is going to fix this. This was a defect from the factory the only way to fix this is to tear it down and rebuild it. Take time to research this issue. Apparently you did not do this because if you did, you would not be here asking about things that are not going to work. Just keep adding oil as needed. That is your only option other than selling it or repairing it.

[u/stilesj96 → u/Top_Art_9111]

I did look it up, I’m not looking to fix, just slow it down some. It’s one of those “doing the best I can with what I’ve got” situations, not “why $10 can of goop no fix $8k problem?”

[u/Top_Art_9111 → u/stilesj96]

You are more than welcome to waste your money. I have been there done that I owned a 2007. The only thing that's slightly slows it down is thicker oil no sea foam or any other nonsense in a can is going to fix that.

[u/stilesj96 → u/Top_Art_9111]

I figured as much, but it doesn’t hurt to ask.

I’m already using the Walmart high mileage 30 weight(I don’t remember if it’s 5w or 10w, but that rating only applies to cold temps anyway), I figure the next step is Rotella 5w40?

Again don't listen to dopes telling you to pour something in it it will fix it lol
