Castrol® GTX® High Mileage motor oil is the leading consumer high-mileage brand. You won't need to worry about using a high mileage oil or synthetic because this is both. It's a synthetic blend engine oil that helps extend the life of your engine by protecting against sludge, wear and burn-off and also liquid engineered to protect your emission system. One of the leading causes of 'check engine' lights coming on in high mileage cars is actually catalytic converter failure, which can be caused by phosphorous in engine oil. While phosphorous is present in all engine oils for its ability to reduce wear, it is effectively poisonous to catalytic converters.

Castrol GTX High Mileage Motor Oil is liquid engineered with Phosphorous Replacement Technology to replace some of the phosphorous with an advanced additive that maintains robust wear protection. When you want to extend the life of your high mileage engine and emission system, and find out how many miles you can go on a high-mileage oil, there is no better choice than Castrol GTX High Mileage Motor Oil.

Solid Purchase
Size: X-Small, Color: Red
This coat delivers strong quality and clean style. The fabric feels sturdy and warm, and it holds its shape well in cold weather. The color stays bright, and the stitching looks secure. The fit is true to size, and the coat layers easily over sweaters without feeling bulky.

This is more like a long cardigan sweater, than a coat.
Size: Small, Color: #2 Blackandwhite
This is more like a long cardigan sweater, than a coat. It doesn't have much structure & the pocket placement is too high for a coat. That being said, it's very soft & comfortable. As far as sizing goes, the sleeves run a bit long, but the coat, itself, runs a bit tight. I'm 5'10'' and a small fit me, but I wouldn't be able wear anything very thick under it & I'm thin. It's light & machine washable. I almost kept it to wear as a long sweater, but it looks like a coat ,so I sent it back. If you're very thin with long arms and don't mind the pockets being a bit high, then this could be a very stylish piece for you. Otherwise, I would pass.

i would definitely recommend. stick with your regular size or size up for a less slim fit
Size: Small, Color: Black
I usually wear a medium, I ordered a small based on reading the reviews. I am 150lbs 5’4”. this coat fits great for me personally. it’s not bulky, it’s not baggy. it is a slim fit jacket, definitely more on the slender side. when i raise my arms above my head , the sleeves do come up a bit. I would suggest sticking to your normal size or if you want a less slim fit with a tiny bit more room, sizing up wouldn’t be an issue. the coat is super soft and has some weight to it. i would recommend this jacket, it is warm and a nice piece for formal attire.
