Oil change should be easy...I had no such luck with mine, as most of you know who follow my resurrection thread....I have now changed oil 2x , and have racked up 0 miles between them....just idling and revving on the lift bars.... Time to change again soon

The problem is that I have no where to work on my car because of where I live. I'm just sandwiched in between other cars. And I have no way of getting under the car.

I shipped my injectors to witch Hunter to be cleaned, and after reinstalling, I was getting 19.9 Mpg. But I'm back down to 9 and not sure what's wrong..

I am more in the use a top grade premium oil and only change it for cause. Change the filter every 3 to 5 thousand miles and top up and the oil should be fine forever. New cars are going to 50k miles between oil changes.

Your either having way too much fun, or something is very wrong, either way its not the oil.

Start a new thread with details on the problem and what your model is, and what the witch hunter report said about your "before" injectors.

Maybe at one point - they're just a brand now. Made by Allied Signal. Their construction is at the bottom of the industry. Don't take my word for it, just google "fram oil filter issues" or "oil filter study" and check it out. 911 guys in particular avoid them like the plague - many documented cases of Fram filters collapsing internally in 911 applications. I only do Mahle filters on the 911 and the 928.

Enjoy your Fram filters, use whatever you want... But I won't use any stuff I consider to be total crap...

Why compromise on something critical that isn't even expensive - just a little hard to source locally => plan ahead.

I have not actually used a Bosch filter for a while, last 5 changes have been Mann (bought a bunch) - so maybe Bosch filter quality has have dropped off (I see some reports of that) - however if you don't like Bosch as a brand - you are already in trouble - there's lot of it in a 928 - much of it in rather important places.

I always tear apart my old filters to see what is in them.. (thankfully so far nothing much) you can really tell the quality by how hard it is to rip a well used filter apart - especially once you have already broken into the can and removed the filter element.

Up until the early 1980s, Bosch was a name of quality. Now it is a name plastered on everything from toasters, to washing machines to oil filters.

Fram makes filters. Period. Fram Good. Me like Fram
yup. the Bosch dishwasher is one of the best in the industry.

and Yugo just made cars and cars only.. so they must be awesome too

I'm providing a link to someone that compared a bunch of brands of filters. He was comparing filters used for Mopars, so it appears Mann and Mahle are not included, but the addresses many common brands available in the US including Bosche and Fram. He also addresses things we normally don't think about such as bypass valve construction. Here's the overview link: Oil Filters Revealed - MiniMopar Resources. Here are summaries for each brand: Oil Filters Revealed - MiniMopar Resources

Look at my previous post in this thread with the video link. The comparison filter they dissect may have had the name removed for legal reasons but it's obvious as to who made that orange piece of *****.

If I were in the middle of an oil change and only had a Fram available at the time, I'd choose to leave the Mahle in for a second round.

I install these valves on all of my cars. Easy and quick, no tools required for an oil change unless you need a wrench for your filter.

I've been thinking of those for a long time. Ever had any seepage issues?

Never had a single issue. Some people are scared to use them because of clearance issues, thinking they'll drive over something and break it. Sometimes you have to explain to an oil change tech what it is. But I've installed them on four cars over the years and have had nothing but success.

LOL, you won't get a Fram POS anywhere near a car I've dealt with and there are a dozen reviews out there showing why. Mahle, Bosche, Wix, Mann are great. Use a good quality, high ZDDP oil such as the 15w-50 M1, Royal Purple, Amzoil, Torco, swepco, or Brad Penn. Don't go for the cheap stuff and unless you are living in Northern Canada you need a 15w-50 or higher viscosity oil.

Of course these threads always bring out a dozen opinions but those above are mine

I love it. I stopped with Fram for a different reason, shards of metal from the threading operation were inside two of the fillters I bought for the Suburban.

... Sounds like the same reason => Poor Quality...?

Well, most of the article dealt with filter surface area comparisons.

Well - in the volume of material written yes - however the revealing bits were in the summary section (linked at the end), besides smaller area in same can at least means lower filtering capacity (may also mean lower flow).


Under the "Filters To Avoid" section:

Fram Extra Guard

Years ago Fram was a quality filter manufacturer. Now their standard filter (the radioactive-orange cans) is one of the worst out there. It features cardboard end caps for the filter element that are glued in place. The rubber anti-drainback valve seals against the cardboard and frequently leaks, causing dirty oil to drain back into the pan. The bypass valves are plastic and are sometimes not molded correctly, which allows them to leak all the time. The stamped-metal threaded end is weakly constructed and it has smaller and fewer oil inlet holes, which may restrict flow. I had one of these filters fail in my previous car. The filter element collapsed and bits of filter and glue were circulating through my system. The oil passage to the head became blocked and the head got so hot from oil starvation that it actually melted the vacuum lines connected to it as well as the wires near it.


Fram Double Guard

Another bad filter idea brought to you by your friends at Fram. The filter itself is a slightly improved design over the Fram Extra Guard, but still uses the same filter element. It has a silicone anti-drainback valve, a quality pressure relief valve, and enough inlet holes for good flow. The big problem is that they are trying to cash in on the Slick 50 craze. They impregnate the filter element with bits of Teflon like that found in Slick 50. As with Slick 50, Teflon is a solid and does not belong in an engine. It cannot get into the parts of the engine that oil can and therefore does nothing. Also, as the filter gets dirty, it ends up filtering the Teflon right out. DuPont (the manufacturer of Teflon) does not recommend Teflon for use in internal combustion engines. Please do not waste your money on this filter.


Fram High Mileage

Yet another bad filter idea brought to you by your friends at Fram! Gotta love these guys. It's a Fram Extra Guard with a weird goo cartridge suspended on the clean side of the filter, blocking the outlet. It's supposed to be some kind of additive package, but if you want a high mileage oil, buy a high mileage oil. I don't trust these guys...sorry.

Wow, I just skimmed over that the first time, thanks for posting it Alan.

What a crazy bunch of crap.

Again, easiest for me both in Virginia and here in Indiana ---- buy the Purolator at Advance Auto a couple miles from here.
Surprise, inside the box you won't find a Purolator.

I stopped using Fram after I read the oil filter reviews I referenced in my earlier post.
