Review of Red Line 11404-12PK 10W-40 Synthetic Oil - 1 Quart Bottle, (Pack of

Customer Ratings:

The car this is used in is a Mercedes CLK430, which factory dictates I need a 0w40. In the summer, it's hot and don't need the 0w weight oil, so I'm only concerned with the 40w. Immediately after changing the oil over to this, the car ran smoother and cooler. It so smooth at times I had to look at the tech to make sure it was running. I've used AMSOIL, Royal Purple, Mobil1 HM 10w40, Shell 5w40 synthetic, and nothing ran as well as Redline.

I've been running Redline synthetic oil in my 5.0 track toy for years now, and despite seeing coolant temps as high as 240 on one occasion and oil temps regulalry as high as 275, my Blackstone labs oil analyses keep coming back with wear on the low end of the normal range. You can run Redline with confidence.

The KN-303 filter is what is used on my 2005 Yamaha R1. The filter has a 17mm lug on the top, which makes installation really easy. There is limited space between the filter and the headers, so being able to use an end wrench to install it is very nice. This saves having to have a special filter wrench for the OEM style filters. It also has a little hole where you can safety wire it for when you go to the track. Very nice filter.

The product from K&N is excellent. It has beaten most of the filters that compete against it in head to head studies. The KN303 is made for the GL1500, 1988 to 2000, but what many rides of newer GL1800's may not realize, it fits their bikes also. The K&N designed for the GL1800, KN204 is shorter and has less filter area. The KN303 is a perfect fit for those wanting to have a little more filter area and still having excellent filtering properties.

I ordered these for my 2005 Yamaha SX230HO instead of using Yamaha OEM filters. I like these better since they have the 17mm fitting at the bottom which makes removing a piece of cake with a socket instead of a oil wrench. I would think these are better filters too.

I use this exact filter on my 05 Honda Silver Wing. Honda recomends Torqing the filter. And the 17mm Nut makes it easy. Bought the bike used with about 2k miles. Rode 1500 miles and my oil is still clean. This is a Heavy filter for its size. Due to the steel case.
