What engine oil/filter combo are you guys using?

What’s your gas mileage like with 5-30 oil. I know the land cruiser uses 5-30 but is also has 8 speeds

 

Horrible like all Tundra V8 trucks.

 

I get it my truck gives me 16 mpg I drive mainly hwy. with limited city. I’m wondering if (5)w30 made it worse than 0w20

 

The 1st Gen is spec’d 5w-30. I follow directions and use what they say. Maybe someone has used 0w-20 and will chime in.

 

Live a little! Rules are made to be broken!

 

OEM filter and either Mobil 1 or Valvoline Synthetic

 

0w-20 while giving an advantage would likely yield less than 1 mpg increase but potentially incorrect lubrication

 

@FirstGenVol What are the Universal Averages in the right column? Is that the quantity of the element typically present in used oil samples in ppm? I assume they read it off an experience curve for the mileage? If true, then your aluminum wear appears to be about 25% higher than typical oil tests, but they make no comment about it.

I have heard engineers say that time was less important on seldom driven vehicles, and have run 18 month or longer OCI in the past. The most interesting comment in your report was the comment below. I had begun to rethink extending change interval due to slight fuel odor in the Tundra oil, but now?...wth? Did you express some concern about running your oil 14 months?

 

My understanding from their website is that the universal average is basically the average from every other 2UZ-FE they have sampled. Apparently they didn't find the aluminum concerning enough to mention. Good question about time intervals. When I sent this sample in a few years ago the Tundra was my spare vehicle and I was only driving it around 4,000 miles per year. I had asked them if it was ok to only change the oil every 14-16 months.

@lsaami and @Festerw what were you aluminum counts on your Blackstone report? John's trying to give me a stroke here.

 

Thanks for your report, and the explanation. Sorry, I didn't intend to create anxiety for you. Maybe 1ppm higher per oil change is not significant, but over a lifetime of changes it's still, well actually, 33% higher than the universal number. Inquiring minds you know.

Doesn't one of Tundras members work at Blackstone?

 

I just wanted to be included in this thread.

 

Little lower.

 

I’d not pay much attention to these Blackstone reports. If the engine blows (even though you’ve been taking good care of her), then there is not much you can do!

Not sure what corrective measures can be done other than using the proper fluids. If those aren’t working, then its time to move on or rebuild.

Wheres my trailerhood brotha from anotha trailer motha? @bmf4069

 

Your wear rate is actually 33% LESS than the Universal Average for 2UZ-FE. Blackstone would/could probably add some discussion about the variability and accuracy of ppm measurements on any one report, and "past results not being a indicator of future performance". As mentioned, owner's shouldn't put too much weight on any one oil analysis report, but elevated wear metal levels are something to be watched for on future reports.

Of more interest to me is if apparent higher wear rate of Erik's sample indicates anything about using a "cheap blend" (no disrespect intended, Erik) versus more expensive branded oil. I use only major brand oil (Mobil 1, Valvoline) even if it's more expensive, but have had an automotive engineer tell me that Walmart's brand is just as good if it has the API rating stamp.

 

I posted mine a little earlier in this thread. Aluminum count is 3 on my Mobil 1 High mileage Synthetic with a FRAM XG filter after 5000 miles.

 

That was 8500 miles Valvoline Synpower 0w-20 and a Toyota filter.

I'm not doing analysis every change just with it being (at that point) near 200k how it was doing. Mostly was curious about antifreeze and fuel to see if there were any issues I could correct ahead of time.

 

I agree to an extent. This test is only going to tell you so much. That being said, for the part in bold they actually have examples on their website of how the test has been used to catch issues before they became expensive problems. They go beyond just metal content. The key there is timing. But I understand if someone doesn't want to spend the money.

For me, I find the test to be interesting and I'm not going broke by doing one every 2-3 years.

No offense taken. I switched to Mobile 1 a year or more ago. I'll likely do another test soon as it's been a while.

 

THAT was some high quality intel that was properly interpreted and applied. Pretty good sales pitch for Blackstone.

Personally, I have never had an oil analysis done. Like PHM, I have believed that if I perform regular maintenance with good products according to OEM recommendations, I'll be fine. After establishing an early baseline, supplemental oil analysis performed occasionally could make a difference as the miles begin to pile up. If any anomalies are observed, then you can test a sample after every future change to see if a problem is developing.

When you've had the analysis, post up the results. Appreciate it.

 

The 0w part isn't bad in the winter if you're living in the north, the 20 is a problem no matter where you go.

 

I'm actually going to this grade in the summer

 

I wouldn’t hesitate to run 0w-30. But 5w-30 is more available

 

Correct me if I'm wrong on this.The larger the difference between numbers means more additives. if that is correct then I would prefer 10w30 since I'm in Florida.

 

10w-30 is similar to a ten weight oil cold, and a 30 weight warm. It has nothing to do with additives.

 

The additives are how they make 30 weight oil act like 10 weight at 0 degrees. The additives in oil is why change intervals are setup. The additives begin to separate around 2700-3000 miles in conventional oil. I'm of the thinking, oil with less additives or oil designed from the ground up with these tolerances (quality synthetic) would be best. The big black clumps you see in engines has a lot to do with those additives

 

I go 15k between changes with mobil extended 5w-30. No black clumps to speak of. The additive package is part of the ANSI from my understanding

 

Synthetic oil can do 15k change intervals and I believe the mobile extended is synthetic. There aren't many true synthetic oil's on the market, I know amsoil, liqui moly and royal purple are.

 

You need to do some research. Multi-viscosity oils are not made by an additive package in the conventional sense. Multi-visocosity motor oils are made from engineered long-chain hydrocarbon molecules that shrink and expand with changes in temperature, resulting in the viscosity changing. Those molecules are an integral part of the motor oil, not an additive.

 

Maybe I'm not seeing it or saying it correctly. But this explanation and my interpretation is additives
