They are gonna get a wake up call as many of these cars have turbochargers and when you start adding boost or parts the oem oil isn't going to work. As far as I have driven and the fact that I definitely get the oil up to temperature brings me to always use a superior oil with a higher performance standard. I'm not leaving any vehicle stock,not driving under 75 mph and not settling on a quart of oil from Walmart to take me the distances I wanna go. The 8w and 16w belong in a bottle of CLP Breakfree,not a car.
. I really doubt car manufacturers will have any of those "lifetime" warranty on their cars when this all takes shape. Remember when 5w20 synthetic blend was the new kid on the block and then came 0w20 and it's high costs to consumers? They raised hell about the cost and so on. Now imagine it all over again with another oil,another cost gimmick at the service shops/dealer. Apparently these oils have been doing this in Japan for quite sometime. However, they don't have many miles on them as the government makes it too difficult with all the emission demands and such. Probably why I was able to find low mileage B16 motors with low miles. I'd like to see these engines after 200,000 on this 16w sewing machine oil. You won't get this far on 8 or 16w oil on factory internal parts.
. The better mpg from FE oils is negligible. But so too is the wear protection of a higher grade oil when not called for by the manufacturer in your region. Both are true but at negligible levels for the individual owner.
