Hi all,

Have 2 Toyotas in the fleet currently. Was looking into the Toyo Filter and overall consenus is positive. I'm aware that they have a higher flow rating but lower filtering efficiency. I'm not usually too particular with filters but this got me curious. For a Toyota, is flow more important than efficiency? Does it matter? I'm torn between these and running PG/Pentius/CQ Premiums. The Tundra is under warranty, but I haven't read anything that shows Toyota *requires* the use of OEM.

Open to feedback, and not attached to either option, thanks!
 
Fram Ultra XG9972 100% synthetic. No longer manufactured but currently sold as a blend.

I run Toyota filters in my Toyota's.

1 has 160,000 miles another has 300,000 miles.

Millions of Toyota's are on the road often times with 250,000-300,000+ miles running Toyota filters, they have a consistent good build quality and they very obviously work perfectly fine and they are available at Walmart.

Just be sure to keep documentation that you did in fact change your oil and filter, but they cannot deny your warranty just for using an aftermarket oil filter they would need to prove the oil filter caused the failure, using OEM Toyota filters just gets rid of that possibility that they could try to use aftermarket filters as a reason.

There was always the debate on this forum indicating for the Toyota filter, that flow was more important than filtering, as you found. But if that was so important for Toyota, why did they (based on a decades old test, not able to apply it to today's filter media) prioritize flow over filtration? Probably because oil flow is more important than filtering. Even with a higher (aftermarket) filtration rate the particles caught are not that high. If the system is air-tight, no wear particles entering into the system via the air intake track, then the only other way to have wear particles entering into the oil has to be the parts being lubricated. And since Toyotas usually run a long time before issues, it means that those Toyota engines are not wearing particles into the lubrication system.

I know I'm captain obvious but had to write that. That's why I think Toyota doesn't prioritize filtering, because it's really not needed. Not in a Toyota engine anyway.
 
There very basic material oil filters seemingly well constructed. Cellulose, nitrile valve, etc. I have run them, nothing wrong, nothing great.

The flow is going to be a function of the delta P across the filter, so until someone measures that its all speculation. There pretty much just a standard cellulose material, so the flow is likely similar to most filters - I don't see anything to say its monumentally better - or worse?

You mean this?

What is the flow vs dP curve of a Toyota oil filter at a defined oil viscosity? And how does it compare to some high efficiency oil filters? Without a flow vs dP curve at a known oil viscosity, it's anyone's guess how flow restrictive they really are. Besides, engines use a positive displacement oil pump, and if on filter has 2-3 more PSI of dP than another, it's not going to matter on bit to the oil pump and there will still be more than adequate oil flow to the system.

Probably because oil flow is more important than filtering. Even with a higher (aftermarket) filtration rate the particles caught are not that high. If the system is air-tight, no wear particles entering into the system via the air intake track, then the only other way to have wear particles entering into the oil has to be the parts being lubricated.
Actually, there are more small particles in oil vs larger particles - and it's the particles 20u and less that cause the most wear. And any larger particles can get smashed up into smaller particles. There is also lots of combustion blow-by and resulting carbon debris from that. And no perfectly sealed air filter in it's box is 100% efficient. We see crud caught in the oil filters used on pretty new and clean engines, so they are always generating debris.
 
After watching an interview with John Duchowski from HYDAC on YT I’ll be running Toyota, Denso, or Mann. Probably use up some of the Motorcraft as well.
