Mobil 1 M1-301 Like the Champion, this filter is made by Champion Industries. However, it uses a unique end plate and a thicker can that make it the strongest filter available for wide-distribution retail sale. It also does not use the fragile paper media of the Champion filter. I’m happy to say that this filter is NOT a fake. It is definitely a unique design. It uses a synthetic fiber element that can filter out very small particles and is much stronger than the fragile, Champion paper media. It is rated just under the Purolator Pure One as far as filtering capability, but is still very much above conventional paper filters. It also has a very strong construction to withstand high-pressure spikes during start-up. Given the choice between the Purolator Pure One and the Mobil 1 filters, I would choose the Mobil 1 because of the restriction concerns of the Pure One and that pesky assembly string. However, as with all Mobil 1 products, expect to pay 2 - 3 times as much for this filter.

Using Amsoil 10-40 and an Amsoil filter, Blackstone said the oil looked clean and ready to keep going at 5.5k miles. Changed the filter and added a quart to replace what was lost to the test and filter change, and kept running it. They were still happy with the results that came at 10k miles. This test was on a a 93 octane APR 1.8T that's run hard constantly.

Been using the 205 filter for 30K. I drive it pretty hard, so far so good.

ive been using the mobil 1 filter, my car is redlined frequently, and has seen the track on numerous occasions, ive had no problems.

I have one on my car and it works very well.

I used to use Bosch before I went synthetic, now I use Amsoil with a Mobil 1 filter, 10k between changes.

I prefer Amsoil and their filter...I drive about 187 miles per day when training and the right oil makes all the difference. I tried Mobile 1 the first time but think Amsoil works better.

Ditto on Amsoil, I go 8k between changes and use a Mobil 1 filter.
