Fram tough guards are OK in a pinch, but never use a regular fram they're absolute junk. Personally i use a mobil 1 filter...anti drain back valve, the can is tough as hell to withstand pressure spikes, and the filter media is top notch.
Any thoughts on Amsoil? I've always used their products in my race bikes and thought id try it in the jeep when I got it. Im running the new amsoil filter rated for 15000 miles with their new synthetic oil. It's rated for 15000 mile intervals but im not going to run it that long. I dont rack up miles that quick so ill probably dump it every 7500 or so.
so base on all of the info what type of filters are the best to use? i just got me a frame filter my self, and by reading all of these info it make me wonder if i should change my filter. i want to have the best of the best out there!
Fram had some QC issues years ago but their current Tough Guard filters filter to 99% efficiency which is better than many expensive filters can. I was an ardent anti-Fram guy for years but I learned last year that my opinion was based on old outdated Internet info. Their current Toughguards are very good and in comparison tests, are more than competitive. Fram invited ten "journalists" to their Ohio R&D facilities last year, I was one of them, and they spent two days on presentations and showing us how they test their filters. They fell on their swords the first day, owning up to a few issues I asked about and explained how they fixed them, but then showed us how some of the internet info was just plain wrong. The other nine were bonafide journalists so I dunno how I got picked but probably because I was so vocal on Fram filters.
Seeing the test results, meeting with their VP for engineering, and learning how filters are tested on their multiple test machines turned me around. I would use a Tough Guard (99% filtration efficiency) in anything I own now. I'm not as sold on their other filters (95%) but for what they compete against, they hold their own.
At some point soon, they are replacing all their current filters with an entirely new line that is all at the 99% filtration efficiency level. No more cardboard in their lower-end filters, which is what many keyed in on. But what's funny about the cardboard (not that it was really cardboard, it just looked like cardboard), was that is provided the flexibility to maintain an effective seal against the filter material. It was a good design in reality but it couldn't hold up to the scorn of those who kept going after Fram based on that cardboard end cap their low-end filter used.
when I pick out a filter for my jeep I want it to have 99% efficiency @20 micron, i also don't need to it be a long drain interval filter (5k is the most ill ever do) and be somewhat affordable (again im not gonna go 10k miles on a filter so i wont spend 10 bucks many companies charge for top tier filters) and I like it to be made in USA
so for me that comes down to Purolator PureOnes and Fram Tough Guards
I also like the over sized filters since they are the exact same filter just 40% larger which is great since it adds more surface area for oil to pass threw and wont build up too much pressure as easily and go into by pass mode (like when oil is cold and thick) also since it is bigger it holds more junk before getting clogged up. best part is they are the same price as the regular sized filter. I know not every jeep has room for the filter but in my experience every 4.0 TJ does.
so for me that means Purolator PureOne PL30001 or Fram Tough Guard TG8A
these filters are about filtering the best (they filter better then the extended drain filters like mobil 1 and bocsh distance at the cost of not being able to last as long) so for my needs i think they are the best filters. if you were someone to go beyond 7500 miles (which i find dumb on the 4.0) then i would start to look at the top tier filters that are more expensive but don't filter as well. there are no "best filter" just what works for your situation.
Nope, i added EXACTLY 6 quarts (letting the jugs drip out completely....im a cheapo lol) and the oil level is exactly at the full mark. I was surprised how well it turned out! (check the oil on a level surface after the engine has been off for at least an hour, otherwise the level will read low due to the oil taking a while to drain to the pan)
