Motorex - Power Synt Synthetic 10W-50 4-Stroke Engine Oil

Motorex Power Synt Synthetic 10W-50 is built for bikes that live in the fast lane — fully synthetic, race-grade oil made for hypersport and high-performance 4-stroke engines. Developed with the same precision as Motorex’s factory racing lubricants, it delivers outstanding protection for engines, gearboxes, and clutches under the most demanding conditions. Whether you’re running at peak RPMs or cruising at steady speed, Power Synt keeps everything running cool, smooth, and consistent.

Why we like it: it gives big-bore sportbikes exactly what they need — serious power delivery without sacrificing protection. The formula’s exceptional thermal and shear stability means it holds viscosity under heavy load and extreme heat, while keeping the clutch feel crisp and predictable. It’s catalytic converter safe and delivers that unmistakable Motorex smoothness that serious riders notice right away.

Why it’ll work for you: Power Synt meets API SL/SN/SP and JASO MA2 standards, guaranteeing smooth wet-clutch performance and top-tier wear protection. It’s ideal for high-output engines where precision lubrication matters most, providing consistent film strength and clean operation even at racing temperatures. For riders who push hard and expect their oil to do the same, Motorex Power Synt 10W-50 is as serious as it gets.

Great fit, truly doesn’t slide off heel

I’ve scoured all the lands looking for a no-show sock that was 1) thin, 2) quality, soft, breathable material, 3) didn’t dig into my feet/heels, 4) doesn’t shrink, and most importantly 5) stays on the back of my heel without a bulky non-slip rubber piece and these check all the boxes! Perfect for low profile women’s work shoes like Keds, etc. Not low enough for most flats though. I wear a women’s size 9.

So good - I’m buying MORE.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I’m gonna give you more detail than you need about why I’m buying these socks again. I’ve been the mom of girl athletes. I’ve been a model and a fashion director. I’ve worn every brand of shoe on the planet and never found a shoe that did NOT find a vulnerable spot on my foot to rub raw. Even my beloved white Jack Purcell sneakers. With that said - I don’t like socks. I’ve bought a TON of them in 35+ years.....all major brands. They shift. They lose their shape. They get holes in them and wear out too fast. Not these. I retired this year, and knowing I’d be in sneakers a lot, traveling, sightseeing ...... I bought these 6 months ago and have worn them constantly. I’ve traveled with them. I’ve washed them in hot water and bleach. The socks are like brand new. They are exactly the right cut so as not to be seen in a basic sneaker. The little silicone patch on the heel stays put. Not once have I had to dig down into my shoe and pull the sock back up. The socks have stayed soft and EXACTLY the same as the day they were new. Like I said - I am back to buy them again. Great quality!

Stay put!
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
Nice and thin, soft, and stay put. I wear an 8 shoe and don’t like a thick sock taking up room. These socks are a bit tight on big toe. Wish they came in large.

The best
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
The best no show socks I have found. Stay in place very well and hold up wash after wash. I have tossed all the other brands I’ve bought over the years and stocked up on these as I was tired of digging through the drawer hoping to find a clean pair.
