Add engine oil!!!

I do wonder if a lot of the people claiming they've never used oil actually check, or of they have the dealer always change their oil and have just never heard anything about it. There is a common issue with the Toyota 5.7L 3UR-FE where not enough of the FIPG seals on the cam towers get applied at the factory and oil ends up leaking out. I had two different Tundras and both had the leak, but tons of people claim they "don't have" the issue, including two people I personally know with Tundras. However, they didn't actually know they didn't have the leak, they just didn't know they did (kind of the absence of evidence isn't evidence of absence thing). When I checked their trucks for them, they both had the leak. Anyway, my point is that people claiming they don't have oil consumption issues might partially be people really just saying they don't know if they have consumption issues.

Not in my case. I change my own oil and check the level about every other gas tank fill.

In reality Jon, who actually checks their own oil these days? We do because we are who we are, but I can't honestly say I've ever seen someone at the pumps checking their own oil. They run inside, buy some crap off the shelves, run back out. Put the fuel hose back into the pump, light up their cigar or weed and drive off. That's what I see.

Yeah I check and change my own oil in all my vehicles.

I don’t check mine at the gas station unless I’m on a long highway trip. It’s not shut down long enough there plus these days you want to be heads up to what’s going on around you when at a gas station. I check it in the garage first thing in the morning to try to get fairly consistent measurements.

It sounds like he doesn't change his oil very often. Not judging of course.

Ha, you're right. He even said he went a long time that oil change. I think the manual calls for 7,500 mile intervals? I've done 5,000 miles or every 6 months on my trucks. I usually only drive about 5-7k per year, so usually every 6 months. I'm not quite at 5,000 yet on my 2024, but I didn't notice any loss when I changed it at 1k or a few dipstick checks since then.

What we found, is that because it had been babied all of those years, that the top of the cylinder walls had the dreaded edge on them. I had broken every compression ring on that engine and the oil rings were toast as well.

Not the reason it had a ridge. But the ridge is the reason you broke the top ring running it to valve float rpm. [ three on the tree] Missed a few shifts, did we? I was 15 once. :crackup:

Toasted oil rings at 70K should have been a clue.

Quick update on my experience, currently at 44,577 miles. SAME issue or concern I should say. When "daily" driving to and from work, oil consumption is what I consider "normal". Oil change intervals at 7-8K. I take about 2 maybe 3 long camping trips a year at about 1200miles round trip. Its during these long pulls that I'm having to add a quart or 2 halfway though the oil change interval. Engine wise I have not noticed a difference in performance so its hard for me to call this an "issue". I just add a quart and keep on driving!

Is all of this with synthetic or conventional oil or both?

I use Mobile 1 5w-30 full synthetic and mobile 1 m1-212a oil filter as well

The manual states to use full synthetic oil meeting the Dexos 1 specification. I’m pretty sure everyone posting in this thread is following that.

Mine burns excessive amounts of gasoline.

Me miss a shift??? Have you lost your mind???

I knew it before I even wrote it. It was going to be either @Grumpy Bear, @KARNUT or @Pryme that was going to call me out. The Hillary proclaimed Dispicables . Anyhow yes.....so I missed second gear on occasion. Not easy to do quickly with 3 on the tree and being left handed. That right hand hadn't been trained very well from day 1...lol either way one of my favorite things to do was just get it moving slowing in first gear, throw it up into second gear, floor the throttle, dump the clutch and slam on the brakes with my left foot. I could sit there with that right rear tire doing the best burnouts ever!! All the while the engine is over revving big time, there was no rev limiter on it. I'm still confused why it started burning oil and running like crap after just a few months of me doing that....stupid 350's...they should have built them better....

I have a better story from my youth. I had a 1970 F250 2wd with a 460 C6 combo with a violent shift kit and the engine was bored 10 over. What an animal. This was in 1997. So it was old even then but the engine was fresh. Anyway I didn’t have a grasp on gearing or rev limits etc and was racing my friends Camaro. A 94 catfish and my old horizontal speedometer was pegged past 100 and I never let off and I heard something and when I exited off the freeway it wanted to die I kept having to give it revs to keep it running and I pulled it into the shop I worked at and the mechanics took the valve covers off and low and behold I floated a pushrod right out it was laying on the block. The most amazing thing? It wasn’t bent it didn’t look bent at all it was unreal and we put it back together and it ran fine holy heck.

I bought a cheap little tach after that.

I loved that truck. Key was on the left. Crazy torque

Broken rings kills compression. Floating valves lowers the float rpm every time you do it. The crap part.

It's a long walk most of the time from fresh to fresh out. You said the oil rings were toast but didn't specify in what way. Expander full of gook, rails stuck in land, ring land drain back slots/holes plugged or bore just so hour glassed everything lost its seal? All of the above?

Given the time period the oil in the bottle was not likely the issue IF the proper grade and service class was observed. HOWEVER, all additives are sacrificial and an OCI repeatedly to long for the service it sees leads. Worsened by a lack of sharp tune. Even 2K can be to long for a motor that grandmother drives 2 miles each way a few times a week to the store, hairdresser and church.
