Whoa there Haley...as long as the viscosity is appropriate, why not run a "tractor oil" in a new car??
Sure, they are forumalted differently. Mineral-based PCEO's are formulated for fuel-economy while still delivering protection for shorter drain intervals, while mineral-based HDEO's are all about protection and engine cleanliness and having the ability to run long drain intervals.
Your "argument" makes absolutely no sense to me...could you please expand on it a little more and provide me with some reasoning as to why you believe this??
In regards to an engine being "dirty", I'm talking about varnish buildup and ring-pack buildup in higher-mileage engines. Sludge-buildup isn't a problem unless your engine is "sludge-prone" or you severly neglect your engine.
Drew...congrats if your families engines are spotless, but I've never, ever seen a higher-mileage gas engine that was ran on a mineral-based PCEO be "spotless", or anything near that, even on 3K drain intervals. They are always covered in a layer of brown varnish.
I guess, in terms of engines, cleanliness is next to godliness for me...as long as the engine has no inherent problems itself, and is well designed, clean, well protected engines run a long, long time before having oil-related problems.
With that in mind, this is why I run mineral-based HDEO's or synthetics.
