diyer2 thanks for sharing. 


Did the other forum share any oil analysis data to show improved FTIR data that would directly affect combustion performance increases? 


I say burn clean fuels, run clean air filter, use best lubricant you can for application and KEEP intake deposits low from day 1. Injector function, free air flow, best ring and valve guide seal will ensure low deposit formation over the life of the unit.  Allow any of those to be less than stellar or a misfiring coil or plug and you'll build carbon fast. 


On a used car this might be helpful.

No UOA, most people don't do this as you know. It was said to improve overall engine performance. With all the variables when talking about anything automotive related it's hard to not take most things with a grain of salt for me. I believe few owners do good/proper maintenance and are fix it when it breaks or trade it off and don't care. I on the other hand try to prevent problems like mechanical breakdowns especially on the road so I like some go overboard on maintenance. To me it's the consistency that makes a difference in the long run, like using Top Tier fuel, proper OCI's depending on the products used. Doing that little extra pays off IMO.

I recently had the dealer do all the stuff they’d been bugging me about since 30k miles. It was in for a starter and front seal leak at 11 years and 120K miles. We were going on a trip I figured what the hell she’s going to keep driving it. The car is a Genesis. After plugs and injection cleaning 6 months later it runs the same and gets exactly the same fuel mileage. I never done this before and the results were as expected. No difference.
