I've beeb running this stuff in my Aurion for the past 2 months. Done 2 trips up NSW coast since and general round about town here in Sydney. What can I say? All seems good. It looks like the genuine product - don't know if there's such a thing as fake? The labels look very high quality/original with like a 'dimpley' feel - strengthening my hopes of it being genuine. The original seals on the bottles seem reassuring. I purchased the M1 EP 5W30 in a box of 6 x 1quart. It's just under 6Lt in metric, but I found, unlike all places saying the 2GR-FE takes 6.1, 6.2? Lt of oil, when changed with filter, Mine, when fully drained and new filter, only took about 5.8L. Even after driving around, most I could top it up with was a 100mL before it reaching the upper level on the dip stick. Yes I drained it fully on a flat surface till there was basically no drip. Shrugs. Oil seems clean as - but it has an amber 'tinge' (spelling?). Apparently what the M1 EP product looks like (found out from half an hours research at the time). M1 EP, or Mobil1 Extended Performance, as far as I know is the highest quality fully synthetic oil available (other then high end specialty oils like amsoil, etc, tho those products are all debatable apparently..) here's an example of the M1 EP 5W30 product that's thankfully available for us. To make it better, Nick from Gl Lubricatants, who's the eBay seller of those items, is an absolute champion! I had him tack a 1quart bottle on my order cause I found out re the 6.1 6.2L issue. His communication was 2nd to none. Pity I never needed it. 5w30 would likely be most appropriate for most ppl's Aurions in AU I'd say. The aussie retail 'fully synthetic' M1 products, containing 'synthn'? or somthing like that, I dunno.. might be same stuff. All I know is this is the US product and there's been tests conducted on it, and it's the bee's knee's, so they say. Best regards.
