Extended oil drain intervals

I'll chime in here regarding oil analysis. I had my Toyota 0w-20 analyzed at approx. 30,000 miles on the engine and 5220 miles on the sample. Blackstone came back and said the TBN was 4.7 and try going 7500 miles on next oil change. In addition, the report said Toyota synthetic has some different additives vs. Mobil One-most notably molybdenum, calcium, and magnesium. I'm for sure no chemist or expert in this field, but have always had my oil analyzed every 30k or so, and it seems Blackstone has consistently given me the go ahead to bump the oil change a little longer (usually 2500 miles). I'm sticking with 5k intervals on my 2012 ls460 until my original warranty expires. I pay roughly $6/quart after tax at my local Toyota store-Lexus has in stock as well but charges about $8/quart.

My Amsoil rep had a van that has over 350k miles with extended oil drains that he uses to sell oil.
Like I said before Amsoil is good oil however I cant stand their multi marketing approach to selling oil as well as gimmicky vitamin supplements. They do get their filters from Wix and Baldwin which tells me they know their costumers expect the highest quality.
I like the fact that Amsoil acknowledged the German Castrol as being superior oil then theirs and went back and re-formulated to be on par.
Off the shelf oils have improved dramatically over the last 10 years and a lot of it has to do with the demands of some of these newer cars. Even conventional oil has improved.

Yeah you mentioned that German Castrol a few times and I did a little research on it - I don't think it's available in the us anymore, but everyone swears by it. Castrol has said it is a different formula than their Edge with titanium product (although they of course praise that product).
I don't think Castrol was trying to make a superior oil for the public consumption because they never advertised it's superiority. The reason why it was king for a long time is mainly because it has to meet BMW specifications. BMWs as well as many other German makes are friction motors and they get hot compared to Japanese engines. This has everything to do with the kind of driving the car sees and in North America we have a mixed driving culture of both city as well as interstate driving.
A3 specification is important in Europe also because they do extended oil drains.
There is a lot more then meets the eye when considering an oil and just by going by the formulations and tests does not give us a clear picture but a good UOA does.

Everyone for a time swore by GC because the results from UOA was overwhelming proof. We can debate what goes into the oil but in the end it's the report that counts.
