Bests & Worsts Reviews from Amazon

I've been using this oil for over two years now, first time I've seen it on Amazon for less than it's at Wally World and it gets shipped to my front door! How good is the oil? Consider this, I do oil analysis on a fairly regular basis through Blackstone labs and I've tested this at 5K and 10K miles (it was changed out at 10K). At both test intervals, it still had remaining life, estimated at 7K at the 10K change out which would make it 17,000 mile oil. I don't go past 10K because I'm old school and remember 3/3000 as the gold standard for oil changes. A couple of caveats - I changed the filter (Wix) at the 5K mark, it's inexpensive insurance to me. I do not buy into the Mobil 1 filter being required and/or superior to a good quality filter from another manufacturer. Yes, I know you're supposed to use a Mobil 1 filter to get "full protection" but if you have an oil related failure at say, 12,000 miles, good luck collecting regardless of which filter you used as they will surely claim you were using it in the harshest of conditions and should have followed a severe duty change cycle. Could be wrong but like most guarantees, there are more reasons listed to not pay then there are to pay a claim. I get back to trusting the extensive oil analysis that Blackstone does. They have no skin in the oil side of the game and so have every reason to be honest and upfront with your particular results. And, in the interest of full disclosure, when I used "regular" Mobil 1 synthetic in the same car (2012 Honda Accord BTW) and sent the analysis in at 7,500 miles, it came back as suggesting extending the interval by 5,000 miles so even the base synthetic is an exceptional oil. Were this not priced so competitively on Amazon right now, I would have stuck with the regular but for essentially the same price, go extended. I will be using it in my 2003 Toyota 4Runner V6 with 120,000 miles on it next and will probably go the full 15K, with testing, in that vehicle as I have a fourteen year test history for comparison purposes, starting with regular dino oil, switching over to Mobil 1 at around 30,000 miles and now going to the extended. I only use Toyota OEM filters and will change it out halfway through the cycle with testing then and at the end.
