Inspect your filters
I would not run those
Update us on what RP/Champ or Summit offers.

I don't think anyone has commented on this yet, but I noticed that per the Ascent tests published here last year that the RP filter he tested appears to have flunked the USCAR-36 resistance to flow spec. From the Ascent chart, the lowest resistance to flow was around 8.8 PSI. Per Service Pro, the SAE USCAR-36 specification put together by Ford, GM, and Chrysler sets the maximum resistance to flow at 50 kPa which translates to 7.25 PSI.I've not been able to find any quoted performance and life specs from seller's websites so for me I won't consider the RP filters. If someone has located specs, please share. Thank you!
Have you determined what it is? The Synerlec or the purple food coloring?I'm allergic to anything RP, so that would be a no-no for me.
I don’t really follow the USCAR stuff, but isn’t that essentially a Ford-only thing? So if one doesn’t have a Ford, this is kind of a moot point?I don't think anyone has commented on this yet, but I noticed that per the Ascent tests published here last year that the RP filter he tested appears to have flunked the USCAR-36 resistance to flow spec.

There would also need to be a flow rate and oil viscosity associated with the max resistance to flow spec of 50 kPa (7.25 PSI). Did they say at what flow rate and viscosity?I don't think anyone has commented on this yet, but I noticed that per the Ascent tests published here last year that the RP filter he tested appears to have flunked the USCAR-36 resistance to flow spec.

Everything I have seen indicates it was produced by the Big Three.I don’t really follow the USCAR stuff, but isn’t that essentially a Ford-only thing? So if one doesn’t have a Ford, this is kind of a moot point?
They probably do, but I have not seen the USCAR-36 full spec, only then numbers that Service Pro published. Perhaps someone on this board has and can educate us?There would also need to be a flow rate and oil viscosity associated with the max resistance to flow spec of 50 kPa (7.25 PSI).

Googling around, looks like USCAR-36 is a voluntary, minimum standard set by Ford, GM & Chrysler, for aftermarket oil filter construction & performance use.I don’t really follow the USCAR stuff, but isn’t that essentially a Ford-only thing?

That would again depend on the oil flow rate and oil viscosity used by Ascent in his testing. If USCAR-36 calls out a lower flow rate and/or viscosity, then the minimum pressure drop in his testing would be lower than shown, and be less close to breaking through the USCAR-36 minimums.Another interesting thing to note about the Ascent chart is that AC Delco and Purolator, who have to comply with USCAR-36 for the OEM business with Ford and GM, look like they designed their filters to test just under the USCAR-36 7.25 PSI spec. That looks like evidence that the USCAR-36 spec and the Ascent test results are comparable.
Really ? Putting you on ignore …Everything I have seen indicates it was produced by the Big Three.
Who do you think created USCAR-36 ?Really ? Putting you on ignore …
I have macro views - you can micro without me …Who do you think created USCAR-36 ?
