It’s been discussed in Consumer Reports, among other articles and among enthusiasts that in many of today’s 4 cylinder engines, the move to 20 grades has increased oil consumption rates in certain motors. It’s also been suggested that over time, these engines that consume more oil, are more likely to end up with stuck rings and deposits, which causes a spike in oil consumption as time goes on. I was thinking about this and I’m not sure I buy it. Modern Honda engines will burn oil regardless of NOACK and viscosity grade. My 05 Accord used oil from day one, but ran like new when I sold it with 180,000 miles on it. Ford tested MC 5w20, which is a blend, and there are many Ford engines (Mustangs included) that run a long time with no ring issues as they age. It seems to me that certain engines have better oil control rings. Negative pressure on overrun and low tension rings are the primary culprit in why most modern Honda’s will consume “some” amount of oil. I don’t see the NOACK/Oil consumption/stuck ring/deposit relationship at all. Thoughts?
