Blackstone UOA 5015 Miles W/ M1, W/Turbo

[turbocruiser]

Excerpt from my most recent UOA (Cannot finger out how to post the whole report - converting .pdf to .jpeg?):

"""Toyota makes nicely wearing engines and yours is no exception. All wear metals read right on average after running the oil about 400 miles longer than average and that is a good sign that no problems are developing in that area. Insolubles, which show oil oxidation, were on the high side high at 0.6%, so the oil filter didn't do quite as good a job this time, so it would probably be a good idea to stick with a ~5,000 mile oil run for now. The TBN was strong at 3.9, showing lots of active additive left. No fuel dilution or coolant was found and the viscosity was normal."""

This was the first time I have ever had the oil up to 5K miles. Prior to that 3K to 3.5K was what was scheduled. Looks like the oil did super well but it also looks like they are blaming a bit of oxidation on the filter? I only use the 20004 and cannot see how that was contributory, but in any event, assuming the oxidation is okay, it looks like M1 can easily handle a forced induction 1FZFE for 5K miles. I think this also proves that the 7.5K or even the 10K schedules some have here would be too much for a forced induction 1FZFE. Anyways, just thought I would share something, any thoughts on the oxidation? Thanks.

I should probably also make a mention that the engine is at 162K and that I ran a can of BG 44K through the system from 4500 miles to 4750 miles and the analysis was at 5015 miles exactly. Also my last TBN which was at 3000 miles was 8.1!!! So, the 3.9 at 5015 I think shows that the additive package will probably wear out way before a 7.5K or 10K change at least on a forced induction 1FZFE. Anyways, just for your enjoyment...

I just had the 20,000 mile service done on my 100 series that I drive in England. It's got the IHD-FTE turbocharged, diesel engine (much more power than my 80 back in the US). The service interval on the oil and filter is 10,000 miles. Obviously they use synthetic and it's Toyota labeled synthetic either 5W-30 or 10W-30 (they use both but recommend the 5W-30 for "severe service"). Anyway, quite a few miles between changes. Unfortunately I don't have an oil analysis to see how the oil is holding up after that many miles. (And yes it is miles and not kilometers.)

Good to hear that you're satisfied with your results and I certainly change my 80 much more often mileage wise but that's just because it doesn't get driven very much.

yup, sounds like the oil had some life left in it. IIRC, I thought the 20004 was way up there as far as oil filters go. Is there obviously better?

Don't know anything much about turbos, so where is the reduced life coming from? Higher temperatures I take it, but where specifically?
(Is there oil lubing or cooling on the turbo itself?)

I do not know exactly what setup TC has but the turbo's bearings are often cooled and lubricated with engine oil, the housing is sometiems cooled with oil also or may be cooled with water,

the forced induction also makes more heat in the head and pistons and can cause more blowby,


TC I would not sweat the insolubles, that is very close to what I normally get,

Miles          % insolubles 
10.1k          0.5
5.4K           0.3
6.3k           0.4
3.9K           0.4
5.2K           0.3

Not too much life left - I think that anything below 2.0 is risky right? I keep forgetting the new measurement method that Blackstone uses but there's big difference between a TBN of 8.1 @ 3K miles and 3.9 @ 5K miles!

My turbo is BOTH oil cooled and coolant cooled (and actually also "air cooled" in the way that the two heat shields are situated and louvered). I also have and really religiously use a turbo timer to prevent coking or cooking (two different things) the oil so it is almost all exclusively the extra heat whilst in operating mode as opposed to a small volume of oil getting ruined in the turbo at each and every shutdown.

Thanks for the tip, I'll try that here...

Good ol M1. I been using this stuff ever since tearing apart a customers Previa van with 150k miles and it looked like new inside. It was actually just a valve cover removal but the valve train looked like new yet. A nice light gold color compared to all the other engines I looked at that used conventional oil which had a lot of crud buildup that could actually be scraped off. Not good! Besides, its the recommended oil for my turbo Evo. Good stuff

[RavenTai]

Nice report.

thanks turbo

RT, now that I paid more attention to it, I realized I created the same amount of insolubles in 5K that you would have had to drive 11K to create! Are you sure that sounds "normal." Never had this till I went to the 5K interval. I'm wondering whether 3.5K is where its at for FI???

depends on which run you are talking about, on the 4K run I made .4 in, following that logic I would get .6 in 6K but I only got ,5 in 10K.


In oil analysis you do not worry about noise, if something is truly wrong it will be immediately noticeable and well out of normal ranges, not quibbling over two tenths of a percent (.002)

I wish I still had the reports from my Chevy, they were Ugly even with the mush higher universal averages that motor carried.
