Hey everyone, With reading on another post about a weird noise I thought I would post this for everyone since I already switched my engine oil. I stumbled across this video last night from Lake, the motor oil geek. He STRONGLY advised to not use the mobil1 0w-40 European formula in any direct injection engine based on his findings. You Tube Here's the video for you all to view yourselves and make the decision on your own. I've already switched to LIQUIMOLY MOLYGEN and happy I did after seeing this video. He has also been endorsed by Dave from Dave's auto center for his research. Watch ..read more

Hey buds Looking fwd to refresh my 2009 C300 with some new extras and make it a bit more fun to keep it for the long run. Besides some new 18” wheels and a spoiler, I also want to straight pipe it to make that V6 sound more fun. The problem I’m seeing is that I can’t find any Luxury model that with a new diffuser. All of them are the Sport models. The issue with the Luxury is that the rear fender is sober / subtle and less sporty / aggressive. It is all flat, contrary to the Sport that has a lip that blends well with a new diffuser. Pic attached. Have any of you done some similar upgrades t ..read more

Hey friends! So this just happened. See pic. Thankfully it happened close to home so I was able to return. Turned it off and on again so it allowed me to accelerate for a few min and then warning light comes again and it doesn’t allow me to accelerate, just moves on drive idle speed. Has anyone experienced this before? I recently took car to replace engine mounts and a pump since there was some oil leaking. I hope it is just something that got disconnected and an easy fix. Or maybe something related to the potential transmission issue I literally just posted a few min ago… Appreciate any fe ..read more

Hi guys New here but so glad to find this forum because I really need some good advice from experts like you all. I’ve had a 2009 C300 Luxury with 122k miles for about 10 yrs. I’ve had an annoying vibration for a while now that is hard to notice unless you drive the car a certain way so even a couple mechanics haven’t been able to identify it. It happens only when I subtly accelerate the car at low RPM’s (between 1500 - 3000) at any speed. I can feel the vibration kinda like in the dashboard. Gonna try to upload a video with it. When I pump the gas hard you can’t feel it. That’s why I just d ..read more
