Oil/Fuel Dilution Concerns...

[SnowmanJPS]

I think this might be a case of it just being hard to read the dipstick, I usually flip my dipstick over and check, it looks overfilled on one side and fine on the other

@SnowmanJPS definitely aware the dipstick gives a different reading on each side, yes. Still easy to notice the increasing level

@MT-Taco yeaaa I know. I gave up checking the oil on my Ford 6.7 because it has the most impossible dipstick to read. As long as I put in the right amount at an oil change, there's no leaks, and any checks thereafter have oil on the dipstick...I drive it and don't worry about it lol. Just never had a vehicle before that noticeably got gas in the oil like this Taco. I'm going to start using my Carista OBD reader to see what the oil temperature is during driving, could be informative. Was hoping to be able to treat this truck the same as my old 5.7 Tundra...i.e. routinely change the oil every 8-10k kms and NEVER bother to check it in between, because I simply never had a reason to. I sure do miss that truck...

Yeah, I’m coming from a 2013 5.7 as well. I don’t do anything different with my 2.4T. I miss the V8 rumble but that’s about it.

True, however, we all have low tension piston rings. You get only 1 chance to break in the engine correctly, seat the rings. The piston rings and cylinder bore surface is where the engine life happens.

All great information and why I joined this community. I know this can get in the weeds but when you spend 70k for a truck you should do all you can for it.

Another point is all the engine recalls from Chevrolet and the Tundra. Chevrolet is hit with a massive engine failure due to crank shaft surface. So all the cats out here that think this is crazy talk, just go find a Chevy guy going through this.

In my opinion, the weakest link of the T24A-FTS is the open deck block. This will only become apparent for the guys trying to get a lot of power out of these via tuning.

Otherwise there's really not much to go wrong. It's one of the most simple gas turbo engines that's been put in a modern vehicle in a while.

When you compare it to the B48 (BMWs 2.0L 4 cyl turbo) it's caveman tech.

How many of these trucks aren't going to break in properly? Probably not many and the few that didn't, won't be burning excessive amounts of oil until 100,000 miles+

Cylinder wash-down is a thing... Especially more so for you hybrid owners. That's fuel sprayed into the cylinder and not fully burnt. Per the comments, short trips where the engine is not fully warming up. Definitely a thing. Car Car Nut on Youtube had a Toyota in the shop for that. Older model, non-hybrid. If your interested:

I think your comments are spot on in my opinion as well. B48 garbage anyhow. BMW went down hill with suffing that 4-banger in most of their cars, replacing their six's. That said, I think T24A-FTS will last quite a long time with most of the owners.

Per your comments. I agree about the open deck, and unfortunately we are all dealing with low tension rings in all of these cars these days, so that's also another concern on my part. That and carbon buildup on the oil control ring. However thankfully this engine also has port injection so that should keep the garbage washed out of the cylinders.

Just remember, the old "Italian tune-up" will keep your engine clean engine especially if you baby it all the time. My 2 cents worth.

B48 garbage anyhow

I think the core engineering of the B48/58 is fine, it's just all the supporting stuff that ages poorly (usually the turbo coolant lines). By ages poorly I mean you'll have leaking hoses at 100,000 miles/10 years.. which I mean wouldn't surprise me on any engine.

And BMW owners aren't known for doing preventative maintenance or opening their hood at all, to be honest. Enthusiasts aside of course.

How Toyota got away with only PCV and cats as the emissions equipment on the T24A-FTS is also very impressive.

No EGR, no secondary air pumps, just PCV and cats.

I don't know how they did it lol
