This is my fifth UOA on my 2002 Toyota Ipsum 2.4L (2AZ-FE) done using Schaeffers/WearCheck kit. Previous four UOAs were by Dyson Analysis. Latest results on the right, oldest on the left. The trace water contamination is probably from leaving the car sitting on the driveway for 3~4 weeks without starting.

Wheres the anti-20wt oil crowd?

Looks good.

UOA is the only way you can tell how good the oil is.This is a really good UOA.Fuchs 0w-20 is one of the best oil you can buy.

You will not that some of us that are not huge fans of XW20 usualy recomend Redline or Fuchs for applications not calling for an XW20!!! If you are going to bet on something best to bet on proven winners!

Ken4, What ever you do stick with robust XW20 oils for that engine. Toyota has said that the 2AZ-FE engines built prior to 2006 should not use 0W20 or 5W20 oil as lubrication failure of some componets could occur. I would venture to guess that Valvoline 5W20 would not give such good results even if time in use was cut in half.

Ken4 what type of oil pressure reading do you get on that engine with this oil? What type/brand of oil pressure guage are you useing? What size adapter did it need? I am thinking about adding one to my car but all the local ones are for Domestic products with SAE size fittings and threads.

Trex, wearcheck only mentions oil is suitable for continued use but did not say how much longer.

JB, Toyota Japan does recommend 5w20 for the 2002 Ipsum 2AZ-FE according to the owners manual. I dont have an oil pressure gauge on this car. But on my older 2000 Camry 5SFE with defi oil pressure gauge, I get adequate oil pressure with 20wts, well within specs of the haynes manual. And I've taken these 20wts all the way up to 118C with constant high speed driving (~140kph) with no problems. For an oil pressure gauge adaptor, you will need a 1/8" npt T-adaptor. You connect the T to the existing factory oil pressure sender. I recommend you get the high quality gauge from Defi. Alot of cheapo gauges out there, come with crappy oil pressure senders that are not accurate or lose their accuracy very quickly.

Ken:

Overall, the numbers look good, except for the Si. I do wonder, however, why your particle counts are so much higher than the ones I just got from my VQ. Yes, they're very different engines, but still... What oil filter did you use?

For reference, here my PCs (from my most recent post in this subforum) :
code:
PARTICLE COUNT DATA
2 microns or less = 833
5 microns or less = 308
10 microns or less = 85
15 microns or less = 33
25 microns or less = 7
50 microns or less = 0
100 microns or less = 0

Toyota Denso 90915-10004 (yellow foam type). I have no idea how to interpret particle count data. This is my second time using wearcheck/schaeffers kit, the first was a corolla and it had similar particle count results. Looks like wearcheck uses the same particle graph for all vehicles.

Does it means that with increase particles count = bad oil filtration? What exactly does particle counts mean?

Oh, i did a search on particle counts and this is one interesting result: http://theoildrop.server101.com/ubb/ultimatebb.php?ubb=get_topic;f=42;t=002362#000002

Ken, Trex:

The ISO codes are helpful in interpreting, but in the end, they are just an interpretation. One would hope a meaningful and helpful one. I'm not sure when the numbers increase to the point where one can say that filtration becomes "bad" for any particular engine. As I think of it (this is just me picking up pieces of info and applying some reasoning and thought), several factors contribute to the outcome. For example, how big are the tightest clearances in a particular engine. I would think that any particles smaller than these clearances would have much less potential for doing damage than the larger ones. Another factor would be what the particles are made of. Softer, easily fragmented particles, without the same potential for damaging engine parts as would harder ones. Again, these are just my thoughts. I continue to pick up bits of info as I find 'em.

Any experts hiding out there who'd like to chime in? Yeah, Ken has much more particles than I do, but his wear looks OK. Perhaps this engine/oil can carry that loading of particles without a problem???
