Here is a question for diesel mechanic. Is it true that diesel fuel economy suffers due to finer filter use?Are this filters any good? Anyone out there with good (bad)experience regarding Finer filter?

Brian i have a 92 4.2 diesel patrol non turbo i was lacking badly in power so fitted extractors bigger pipes,
snorkel, which helped then i fitted finer filters and noticed a big improvement in power and fuel economy. Like any thing u have to do regular serviceing. In the long run i have found these filters cheaper to run than the originals, my opinion i swear by them. Col

Sorry to tell you this Colin but you are dreaming!! There is no way that an oiled filter will give you a big improvement in power and fuel economy over a paper filter. Just think about it - all a filter does is filter the air. If either type is blocked it will reduce performance and economy but if both are in good condition I categorically claim you couldn't measure the difference. Do you sell them Colin????

I have been using Unifilters (similar to finer filters) in my GQ Patrol 4.2 Diesel (no turbo) for some time now - about 150,000 km. Previously used on a 2.5 Turbo Pajero. Noticed slight improvement in both power and fuel economy compared to standard paper element filters. The BIG difference was in dust retention particularly noticeable in the Patrol pre-cleaner. Nothing or only very fine dust gets through to the main filter. It is also a lot cheaper if you are prepared to do the servicing In dusty conditions I also run a Doaldson pre-cleaner on top of the
snorkel and finds this reduces the clogging. At low speeds this doesn't affect performance.
Regular servicing using the proper oil is a must.
Use the wrong oil (eg.engine oil) and you will have economy problems. I carry a couple of spare foam bands. This is convenient as far as space is concerned compared to carrying spare paper elements.
