Tundra Air Filter Test

[mitchr]

We shall see. So far, I think it's quite easy to prove that running 10k intervals with synthetic is not hurting a thing.

I think that may be true with your driving conditions, but I think alot of us would be wise to change with less than that. I change every 5,000 with the 5w30 mobil1 synthetic due to the terrain and short trips. Just my .02.

I just mailed out my 30k mile oil analysis. Cant wait for results.

A quick recap....

First change at 3k to synthetic.
second change at 10k oil analysis excellent with very low iron (super magnet drain plug)
third change at 20k (slightly elevated silicon, scolded by george for not changing air filter sooner. live and learn)

fourth change is on its way to lab now. We shall see.

All stock air filter. Mobil 1 5w30, super magnet drain plug.

let you all know when i know.

Thanks george. Im loving it at Netjets (executive jet). Great place to work.

My truck has just under 14000 miles on it.

Several questions:

Why the switch to synthetics? What is the advantage?

I take my truck to the local Toyota dealership for oil changes.....do the dealerships use synthetics?

Is Mobil 1 the synthetic you guys recommend?

Why use a super magnet drain plug? Where can I purchase one to fit the Tundra's oil pan?

Any help you guys can give me would be greatly appreciated.

THANKS!

Well, the synthetic debate is a long one. I prefer it because I believe it is a better lubricant. You can just tell when you pour it in on a cold day.

You can get the Super Magnet drain plug at www.avlube.com

It may be overkill, but so is a 30 thousand dollar truck. Cheap insurance.

Your dealership is MOST LIKELY NOT using synthetic. I do it at because I have near ideal driving conditions to do extended drain intervals. I am currently using 10k miles per change.

Upon looking at my oil anyalysis my USED oil came out of the case with more additives in it than conventional oil has when new.

Just my .02

This is another long debate that will never end. The short answer is that for extended drains AMSOIL can't be beat, and for regular change intervals Mobil1 prices can't be beat. For 98% of the population, these two criteria is all you need to know.

Mobil 1 oils meet the European specs ACEA A3-02 & A5-02 for extended oil drain intervals. They don't talk about that in the U. S., because none of the auto makers do extended ODI. Why?...probably because the public is still believing JiffyLube that you need to change your oil @ 3000 miles. Well, you don't, unless you think JiffyLube and their owner, Pennzoil-Quaker St. Co. (soon to be Shell) needs more profit.

Here are the results from my 30k mile oil change.

Oil Analysis

Interval was 9500 miles. Mobil 1 oil and filter.

Levels are good. Still have a slight airbox leak it seems. Our resident guru george told me to change the air filter again.

The changes are expensive.. but with extended drain, I think that I am providing better than conventional protection for the same money.

Just my .02

I noticed that Iron, Magnesium, and Calcium have trended upward. Are the increases statistically significant?
I expect Iron is wear off the engine, but what is the source of Magnesium and Calcium? Is this bad?

The Magnesium and Calcium are part of the additive package and I'll bet this last oil change interval was using the newer Mobil1 with a different additive package from the previous stuff.

This is the kind of info that can help all members. Thank you all for this study, it may not be the most accurate scientific study, not that I could do better, but it is much better that no study at all. Will there be a study on different oils?

The following link is an on-going air filter test that I came across at another automotive site. The data thus far is interesting.

Very interesting. Where can I get one of the oil test kits? I'd like to send a sample of my oil when I change it next month.

Is there any future testing planned with offroad driving? Thats going to be the real test. Did you notice any differences in milage?

[nhparrot]

No there are no plans to test with offroad driving. Final test planned is with a K&N filter. No I did not notice any mileage differences.
