Marvel Mystery Oil lubricates the entire fuel system-fuel pumps, fuel injectors or carburetors and the top-portion of the cylinders. These are areas, that by design, motor oil does not reach. Using Marvel Mystery Oil in your fuel extends the life of these vital components by providing them with lubrication that fuel alone does not provide. Marvel Mystery Oil reduces and prevents varnish and gum build-up, two key contributors to robbing engine performance. When you shut off your engine, a minuscule drop of fuel is left at the tip of the fuel injectors or carburetor jets. This minuscule drop of fuel then solidifies into a varnish type residue. Over time, the accumulated varnish blocks the openings of the injectors or jets, contributing to lower performance and fuel economy and shorter life of these components. Spark plug life is also extended by using Marvel Mystery Oil in your fuel. Marvel creates a cleaner burning cylinder environment that reduces carbon build-up on spark plugs resulting in better firing plugs that increase performance and durability. In addition, Marvel Mystery Oil improves fuel mileage by reducing internal friction in the engine.

Surprisingly good shirt for the price
Fit Type: Regular Fit, Color: White, Size: XX-Large
I’m generally pleased with my purchase. I got a 2XL because the website it would fit my neck. Around the waist it fit similar to Amazon Essentials work shirts (like mechanics use which I find comfortable). It was snug around the waist when sitting, but I can’t complain because I have a belly. I did find the neck snug when buttoning the top button so it means the neck is 18 or 18.5 and I wear a 19/19.5 to have 1-2 fingers space in the collar. The shirt is surprisingly thick like Amazon’s work shirts, much thicker than other dress shirts from another brand. And I am pleased that this shirt has button holes like other Amazon shirts does, all vertical button holes except the last one at the bottom which is horizontal. That feature keeps the shirt from unbuttoning itself during daily movement at the office. A very nice feature! I was a little disappointed in how it was packaged however but I have to press and wash it anyway.
