Product description

The Boss B6566-BK Horizontal Mesh Back Task Chair is designed with comfort and ease in mind. At its core is a synchro-tilt mechanism that allows the backrest and seat to tilt in unison, with the back tilting more than the seat to support a natural recline. Tilt tension is adjustable, so you can dial in how much resistance you feel as you lean back, and an upright lock holds the chair in position when you want to stay upright.

The chair pairs its mesh back with adjustable arms and a pneumatic gas lift for quick, tool-free height changes. It rides on a 27-inch nylon base fitted with 2-inch dual-wheel nylon casters, and it carries a weight capacity of 275 lbs, making it a practical fit for most users.

Works just like the Mercedessource guy said it would.
Size: 5 Liter
After viewing a Mercedessource video (trusted Mercedes repair advice Youtuber and blogger) on which oil he liked for higher mileage Mercedes he pointed this out Semi-synthetic 10w-40 out. Called it “muddy” oil. Said it possibly helped with small oil seal leaks and seemed to slow oil loss in higer miles Mercedes. Also made the engines run more quietly. So I have been using in my wife’s high mileage Mercedes (185,000miles W211 2004 E500 4matic) which we baby and I work on. A true very high compression super car, everything he said at Mercedessource has turned out to be accurate. No more leaks. Quiet lifters. Cooler running. Wow. I had been using Mobil 1 full synthetic 0W-40 European Car Formula exclusively but tried this for the seal protection. Works great and no, it is not Mercedes spec but I will see when the harsh Utah winter hits. May switch to the Liqui-Moly 5W-40 Leichtlauf full synthetic (which does meet Mercedes 722.9 oil spec) for winter (I change the oil every 6 months regardless). Thanks for reading.
