2019 Ranger Engine made sludge

[TJC]

I learned a long time ago to not trust any mechanic. If I must take one of my cars in to a dealer or mechanic, I give them one task and then immediately check to see if it was done.

I tried the comprehensive approach, Change all fluids; coolant, engine oil, transmission fluid, diffs, xfer case, brake and PS fluid (My own personal 50K checkup).

Got my truck back with oil changed, but PS had not been touched, rear diff didn't get the friction modifier added, the coolant had rust in it and xfer case and front diff untouched. Brake fluid had been topped off, but not flushed.

But I got billed for it all! We worked out the differences, and I took my truck and did the work myself.

It is difficult to find good honest mechanics.

Re: Engine oil changes

Fully synthetic - every 5K miles
Regular oil - every 3K miles

Re: Auto Transmission Fluid - every 30K miles
Although my 2020 Ranger didn't like waiting that long. I should have changed it at 5K miles, had issues for 15K, changed the fluid and added LubeGard Platinum at 20K miles. And it is back to acting normal again.

At the first hint of trouble I will change it again or in 20K miles. At 50K the filter and PPE deep pan go in.

Everything else - every 50K miles

I am at 21k now on an Amsoil, but I changed the filter at 10k
LoL

At 76k but I changed the oil and filter every 5k since new. It's get too dark to be comfortable going past 5k

Interesting that the intakes valves didn't look too bad carbon-wise, considering 104k.

I noticed this as well, and this was on an abused engine. Don't think I'm going to be wondering when I need to get my valves cleaned anymore. Might try an endoscope at 100k to see how much buildup is on them.

100k isn't bad, my buddy just bought a 24 Tundra for his exotic car hauling business. Ford guy all his life, and had some issues with his last 22’ F150 and decided to try Toyota. At 30k miles the engine seized on the interstate while he was on a run. Total crankshaft failure, but not supposed to be part of the current recall. Apparently, Toyota missed a few units because this failure is the same as what is being flagged. He’s coming back to the light and just ordered a 25’ F150 !!

I actually thought the engine looked quite sturdily built. The only thing was I also surprised to see an open deck design, better for cooling I know, but also harder to seal on a turbo engine. Still as blown head gaskets don't seem to be a major problem with these engines despite the boost, then Ford must have got the casting accuracy pretty good.

Yes Toyota seem to be going though a bit of a rough patch with their engines lately. In Aus they replaced the ever reliable 4.5 litre V8 diesel in the Land Cruiser with an all new turbo 3.4 V6, power and torque is up but already the stories of issues are beginning to creep in. Prices and sales of second hand V8 Cruiser wagons have soared.

I personally think the 10,000 mile oil change the oil life monitor is to long for a turbo, direct injected engine.

Volkswagen, whose engines have been turbocharged for a very long time, also have a 10K oil change interval and minder setting. This has got to be coming from the oil manufacturers. Full synthetic, best additives, blah blah blah. I always changed it at 5K, and I'll do the same with the 2.3.

I used this stuff every 10K in the GTI. It works. I removed the MAP sensor and sprayed it into the intake port.

It is hard for solid oil to atomize and become "blow by" in the PCV.

I can't remember having changed any oil when I was young...that still haunts me to this day...

If you look at OCI intervals for autos used in the European market - in many cases you will find the OCI intervals longer than that of the NA market. You can read about some owners here changing oil at 3k - 3k at one time was a common OCI in the US , but a lot of improvements have been made, specifically in lubricants but also in turbos - water cooling, better bearings, same goes for many newer designed engines - better lubrication, better components - pistons, rods, cranks, etc.

I was looking at it more from the perspective of general mileage and condition. Lot's of folks talking about walnut blasting for DI engines. I'm still waiting for someone to boroscope their intake valves here

We're the opposite as I've always done mine up until 2011. I started with my parents cars back around 14 or 15 and it helped all my friends had older brothers who were huge gear heads back then in the mid 70's. It wasn't uncommon for us to be hanging around (mostly bugging them lol) getting parts or tools and learning how to do things.

When I moved to AZ and was just to hot there most of the time and I had a great shop just down the street. They'd do their version of the "Works" for me with a full synthetic oil for $80.00 OTD. For that price it wasn't worth my time doing it but now I need to find a good shop around here. If I can't I might just start doing them again because we'll have much better weather in the spring and fall here.

I had next to zero guidance...let's say it's a minor miracle I made it senior status lol...
