[Market525]

I am posting 2 OA's at once.

Oil type: Amsoil 0w30 Series 2000
Vehicle: 2000 Toyota Tundra 4x4 3.4 V6
Miles on oil:
10,634 first analysis (44,483/vehicle) oil in service 12 months. Amsoil filter change @ 6 months.

11,567 second analysis (56,051 on truck). 11 months on oil. Amsoil filter change @ 6 months.

Truck has Amsoil dual-bypass setup installed. Amsoil bypass filter BE90 changed annually.

Analysis was done by OAI, in Superior, WI.

I'd welcome any comment on these numbers. Both came back with "suitable for continued use" but as seems to be the Amsoil trend, viscosity has increased, therefore flagging that measurment as "abnormal".

The truck sees 10,000 to 12,000 miles per year, and I live in Maine, so we have a harsh climate. Some days the truck might only see 1-2 miles a day, perhaps consective days. But at least once/twice per week it is driven 20-30 miles at once to hopefully take care of any moisture problems.

Any comments?

Thanks, Steve

Well the oil as usual turned into a 40 wt. oil. Other than that, the results look fine. I guess though none of us know what the filtering does to the overall wear numbers. Looks like you don't have any problems with coolant, or combustion/fuel.

Further evidence that time-based OCI's are pretty irrelevant and only benefit those who are in the business of selling oil.

I think you're pretty much right on the money there -- the viscosity thickening is the only real 'issue' that I can identify. You might have better luck with GC or XD-3 0W30, but the viscosity thickening you are experiencing isn't the end of the world either.

I'd put at least another 5k miles on either fill without any hesitation whatsoever. Or even consider using Mobil1 0W-20 as your top-up oil, as a 'correction' fluid to the viscosity thickening you are experiencing.

I would use Mobil 1 with your filter setup and see the results.

I would try Amsoil Series 3000 5W30! It has an even better additive package! Looks good to me. I too have to confuse though that I do not know how much the bypass filter changes the results.

 

[Market525]

Thanks to all who replied. I must say that I am frustrated with Amsoil's viscosity issue, even though the reports show good wear. Living in a region of the country that has cold/cool weather much of the year, I do not need or want an oil that "thickens" if I can help it.

I used Amsoil 5w30 rather than the 0w30 at the most recent change, and will sample it @ my six month filter change. I hate to admit it , but I am considering switching to M1 on the next cycle, still using Amsoil filters. I have been a loyal Amsoil customer for many years now, but this issue disturbs me.

I will post the results from my next sample w/ 5w30.

Market, you have a good program going so far. I have used that oil for annual runs with less stellar results but it wasnt the oils fault. My humble suggestion would be stick to your program and add Lube Control at time of service and 1-2 oz. per 1000mi. I believe that will give you one heckuva regime. The oil seems to be working well in this rig.

May want to try the Mobil SUV 5w-40. I think with your setup it should handle 12,000 miles interval.

M1 + Toyota = Perfection.

Snoboy, I am interested in your Lubecontrol comment. Do you currently use LC? I've read comments about LC for a long time on this site, but never used it. I thought that conventional wisdom said that once you use a high quality motor oil (Redline, Amsoil, M1, etc) that you should NOT use additives. Does anyone care to elaborate on this issue? I've read some of the postings in the "additive" section, but still interested in personal experiences using LC & synthetics.

Thanks, Steve

I am a new user to LC and to be honest I am not certain it can control viscosity. It will control oxidation which if it is the cause of the thickening would prevent it but most claims I have seen indicate it will not thin the motor oil. But maybe it can help it stay in grade.
The stuff sems to keep my oil cleaner and I only regret not going about it scientificly. I should have run an OCI and done a UOA without it and then did the same thing with it to see what tangible effects it has other than giving me a reason to pull the fill cap every 1k miles

I do like what FP does for m Exhuast however.. very distinctive change in odor.
As a matter of fact it would be scientific if you ran the ATM and performed the same methodology and used the LC then it would show if it can control viscosity. What do you say?
Nice report BTW. I have the same motor in a hotter environment.

Market 525, to the best of my knowledge the reason the Amsoil is thickening is due to oxidation. The LC (especially if used at start of service) will really help to keep that in check. Your air filter seems to be working well... Si #s of 13 and 15 is good for the miles and months on your UOAs. So your oil is not getting affected much from injested dirt. It needs some help to keep insolubles in check. LC (from my very limited experience using it) will really help. As I stated in my first post this is all just my humble opinion, based on my experience, worth apx. 2 cents.
I really like the Series 2000 for fuel economy. Its tough to beat.

 

[Market525]

Thanks for those who responded. I just received my first order of LC & FP this week. I am only 1,200 miles into my most recent oil change, so I will add the LC this weekend. Results in 5 months will be interesting.

I've already added the FP, and am very curious with the results there. Once it gets cold (as it is now) my gas mileage takes a huge drop, a commnet I've seen echoed here many times. Winter gas blend, outside temps, longer warm ups, or maybe a combination of all contribute?

Thanks again, Steve

How's that next sample coming along?

I'm not sure how I missed this one when it was posted initially. I have a feeling if this were M1 we'd be hearing about the high iron, along with the lead and copper...

That is pretty severe use IMO due to temperature. I would be proud of any oil and motor combo that could get through those short trips in cold temps with those numbers. Just look forward to seeing more. That 3.4 probably sees the same loaddd or wieght that my taco does due to the extra weight I have added.

Bringing last year's post back to the top, I have posted a new analysis. One year/ 8,201 miles on oil.
