If you are going to ask such a question, it seems like you might post a few links to sources which support your position.

I see this all the time. "This or that vendor's synthetic oil isn't really synthetic." But rarely do I note any sort of reference to credible sources making a clear statement on the matter, based upon clear evidence.

Besides that, I have to wonder why there's such a focus upon what's thought to be in the oil, and such a lack of focus upon how, empirically speaking, the oil performs relative to other oils.

That's why people become so weary of oil threads. There's always a lot of bluster by folks who imply they have the facts in hand. But rarely is there any actual meat to the claims.

If someone made a questionable or surprising statement, I too would ask their source and then perform some research, myself, to validate. The information is out there in foreign MSDS (typ Korea and Japan where full disclosure is required) The P/N are the same as North America, so we will assume its the same formulation. This issue to me is consumer deception and cost. The Mfg cost on a group III base stock are 1/2 that of a PAO or PO Ester. Europe does not allow such foolishness as labeling a conventional oil a synthetic. I would post the PDF file but EXxon-Mobil tends toward RTF HTML not downloadable PDF.

IN North American market, synthetic oil doesnt have to be real synthetic. Pretty much a joke - on us. High detergent / long drain "synthetics" can and do show higher engine wear than your 2 buck a litre conventional petrol oil. The detergents compete with the extreme pressure boundary additives (zinc compounds). High detergency is not a plus on a passenger car or race car.

Here is a Castrol true synthetic that you can buy in the US, (I usually find it at AutoZone), but yeah its made in Germany. http://www.bobistheoilguy.com/forums...&Number=718643

I'm so close to trying Amsoil, looks like it is worth a try.

What criteria do you plan to use to evaluate Amsoil if you try it?

I use 4 quarts of Mobil 1 5W-30 oil with a Purolator Pure One filter PL14476 from Advance Auto. I use ramps, oil filter wrench and a 14mm wrench to remove the drain plug. Advance Auto and Autozone will except the used oil for disposal.

my 2010 sedan seems to take 3.25 with filter also which kind of puzzled me since it says 3.9 in manual.....i did notice when brand new it registered way over the full mark so....which should you go by......car was level when changing also

My 2010 was overfilled too.

Well I put Agip full synth in my bike... BMW stealers sell a Castrol full synth as well... do ya really want to spend $20+ liter though...

I'd consider it if i didn't need 4 changes a year.. (and thats changing at 10,000kms intervals instead of 8,000 with synth)

bmw 5w30 retails for 6.25 here in central illinois. I buy it for about 5 per quart. the stuff thats $20+ is castrol motorsport TWS 10w60. thats only for the M cars, probably a little too serious for the yaris!

(I used to work parts for BMW when we still had the franchise)
