Supertech oil filters

I guess I would trust Champion to test the flow characteristics and design a filter that works properly. While the media/design may not be the same as the M1, they make that filter too don't they?

It's rated 94/96 about the same as the AAP Total Grip which I like. I've got no problem with them for a 5K OCI. Bill's run them farther with no issues.

Don't buy it if you don't like it, riverrat. Millions of units will roll down the road ..just like they do on Frams that few of us will ever use because we don't care for them.

Most truth said on this thread yet.
 
+1, The only filters I use as often are the FL820s for my F150 and the Purolator Premium filters on the BOGO deal at AAP. Other than that I use the ST filters and they have been great!
 
Rethinking my post a bit ..

Riverrat, I think you focus on this attribute needlessly. There are other factors that trump this (if one views it as that) limitation.

It's one more "I don't buy (insert filter) because the inlet holes are too small".

Take a look at a Permacool sandwich adapter sometime. For the vast majority of engines out there (no- not "all") that little tiny winy poppet valve is all that's needed to provide full flow with only a 2psi alteration(elevation or drop) to the entire fluid circuit.

In light of this, keeping in mind that I voiced the same type of concerns early in my exploration of these types of topics, why would I ..or why should we, worry about this minor difference?
 
How do we know this filter doesn't make some cars(like GM) go into bypass more often in the cold winter months trying to force that oil by that pathetic space??,i think it would, you guy's run these filters,more power to ya...
 
Well, the same could be said for any other filter ..under any number of conditions.

..but..if you're of the belief in the difference between "free flowing" and "highly restrictive" filters ..that are spec'd for the same exact cars ..........by every filter manufacturer

..then you would probably realize that the lack of a gap is trumped BIG time by the media. Try a time test with two ST's cut open. Plug the center tube opening and pour oil over the top. The can side of the filter will fill freely. Now put a funnel in the center tube of the other ST ..and see how "freely" oil enters the can side from the center tube end of it. You'll over flow the center well if you pour in enough oil before you fill the can side.

Can gap wins.

btw- media, by itself, is highly restrictive. Just see how long it takes to fully pre-fill a filter. Pour ..wait...pour ..wait..pour ...wait. The only thing that changes while running the engine is whether the pump is in relief or not. If the pump is not in relief, there is just about the same "back pressure" on the other side of the media as there is supply pressure.

There can and will be exceptions ..but they are just that, exceptional.
 
Absolutely. It's even less of an issue since the fluid will accelerate when encountering a choke. Under gravity flow, it will back up/slow.

Really, though. It bothers you enough ..so I can fully support your decision to buy something else. They're not a premier filter. They're a value priced filter and have had price increases that have caused me to seek other filters for that type of service.
 
I don't think it would be less of an issue just the opposite,it would be the same as if 100 people were in a room fire alarm went off and all 100 shot to the door,now everybody can't get out at the same time doors only so big. make sense???

same scenario with cold winter oil at start up.thats why i always like running over sized filters,less restrictions.(bigger door)

I do agree on the oversize, but when the oil is cold and the relief in the pump is in use, then all media turns into a fluid sail ..so to speak.

Media ..all by itself ..draining into atmosphere is a WHOLE lot more resistive than air. It doesn't really matter what media it is ..some will be denser fluid sail ..and some will be a less dense fluid sail.

If you're lucky, there's an equally hard to move static column of oil on the other side of the media to shore it up. If not, or the flow presented goes too high, it will hit the spillway (the bypass).

I don't buy them.
But since this is a discussion, I have now added some information for people's approval or disapproval. I didn't post this for those who are going to buy it no matter what or to offend anyone. I don't care what filters people use.
But a question was asked and I answered with my concerns having cut a couple open and made measurements. I'm sure they work, and that Frams work too. Some filters are still better than others and I am concerned about the gap. Thought others might like to see it. This is supposed to be a fun forum with good info, photos, and (where possible) hard facts to take or leave, you guys.

One of the reasons I use Supertechs on my Dad's Blazer is the oil pressure comes up faster and there is less cold start knock in cold weather. I attribute that to the plastic cage allowing quicker oil flow.

If the inlet side was a problem, the exact opposite would be happening on this truck.

Lets see some pictures of other filters and the "gap".

Try cutting a Fram Tough Guard open. There's hardly any gap there as well. Tru cutting a non-ECore Champ open.

You guess it, hardly any gap.

Yeah, I wouldn't use those kind either.
Go and take pics of Wix, Denso, Purolator, (and Pure One), Baldwin/Hastings, Mobil 1, and post 'em here.
...We're waiting...get on it, boy.
 
I've had a hard time cutting filters without the can getting knurled inward. I often have a hassle getting the guts out. That's how limited the gap is in the EaO and M1 filters that I've opened.

Yes. It is. That's why I rethought my post. Sometimes I get whipped up in OT&G and the mania carries over. Sorry.

I still think your concerns are unwarranted ..but they're your preferences ..so buy as you see fit.
