Pre-approved Hometown Charities may be selected for donation depending on retailer participation. ^Subaru will donate $250 for every new Subaru vehicle sold or leased from November 18, 2021, through January 3, 2022, to four national charities designated by the purchaser or lessee. ‡$1 helps provide at least 10 meals secured by Feeding America on behalf of local member food banks. Whatever comes first concludes the warranty. ***Limited warranties are contingent on age and mileage.

I run the recommended 5W-30 in my Miata and I doubt modern angines are going to be happy with anything thinner than a 0W-30 over their lifetime.* Manufacturer's suggested retail price does not include destination and delivery charges, tax, title and registration fees. Modern engines use smaller, more heavily loaded bearings to achieve best fuel economy, which compounds the problem of specifying thinner oils. Most engines will far outlast their warranties, so the manufacturer can decide to reduce engine life to increase sales of more profitable cars. Good CAFE numbers allow the manufacturer to sell more of their more profitable large vehicles. The overwhelming consideration is that car manufacturers need to be able to post the best possible fuel mileage and engine longevity may be sacrificed to that end. No responsible organization would randomly recommend a lubricant that was not tested to their satisfaction, and I doubt they would accept less than equivalent or improved service and engine longevity. I'm sure there has been much testing and anaylses done by the auto manufacturers and motor oil producers already. But wait - these items are mounted in rubber, so maybe you could run these tests! It would be illuminating. Unfortunately, you probably can't run this kind of test with the transmission installed since the crank would be grounded through the pilot bearing and the transmission bearings to the shift linkage, the driveshaft, the differential etc. When tested in this way, the floating crankshaft put out a voltage proportional to temperature and in almost all cases, when contact occurred, it was above the melting point of the bearing material. And of course, the crankshaft isn't the only wear item, in some cases the load on exhaust cam lobes is much higher.Ī similar test involved calibrating the bearing and crankshaft as a thermocouple for voltage versus temperature. I would love to see this kind of test on engines running 0W-20 - I bet most would short out often. This only happened under sudden application of a heavy load. If the oil was too thin, they could detect momentary short circuits caused by metal-to-metal contact between the grounded bearings and the floating crankshaft. Once the engine started, the oil film was usually enough to maintain complete electrical insulation of the crankshaft. Quite some time ago, one of the tests done by researchers involved making a slip-ring connection to the crankshaft and another solid connection to the block of an engine run on a dyno. It would be interesting to do an ohmmeter test on engines running thin oils.
