If you don't prime your oil filters..........

Any engine biulder would recommend the same. I do it cuz I've been a professional mechanic for over 30 years, makes me 'feel' better.


.....funny thing, I started this thread as a joke after a few beers yesterday, some folks got pretty serious!

 

I even go as far as placing these Moroso pre filter screens between the filter and cyl block filter pad . These pre filter screens protect down to 280 microns

 

That moroso accumulator I jokingly suggested earlier is a killer add on for race motors. I never see less than 40psi at startup on my 604bbc

 

It will restrict the flow causing your engine to self terminate

 

I’d bet on a 280micron pre filter reducing flow far less than a 5 micron paper filter

 

Oil filters are a scam to get you to buy extra stuff you don’t need started by big corporations. You will get the best lubrication if you bypass your oil filter completely allowing the oil to flow unrestricted. Your engine will last 500k. I promise.

 

That’s why I just run a toilet paper roll filter system

 

Totally unnecessary.

 

Remember when filters were changed every OTHER oil change.

Save a quart of oil each time ;-)

 

The old-skool helicopters rocked those disk stack-up filters for the transmissions, Bell, Boeing. some planes still use them for the primary airframe fuel filter.

 

I pull the filter every month and if that pre filter works as intended it will trap metal shavings and quickly allow me to see if the engine is hurt

Yes that stainless steel screen won't affect oil pressure

 

Will this extend my oil change interval to 25k? Guaranteed?

 

It does a bit as 'pressure' is resistance to flow however the disks are quite efficent with a high flow rate

 

How often do you change it out? Is it by mileage or when all that's left is the cardboard?

 

35k if you use mobile 1

 

Cool. What if I use Amsoil? Lifetime fluid?

 

I guarantee it will last the “life” of the truck.

 

Cool I'll start on that tomorrow morning. What kind of MPG did you gain? Is this the rumored Prius mod?

 

Is it Friday yet? There’s got to be a Friday around here somewhere, I can smell it.

 

I've done oil changes for this generation Prius for a relative. It was also super difficult to remove the filter housing. I redid the oil change after 10k miles and it was difficult again. I was the last person to touch it. Its just the way its built apparently. I did resort to using my impact gun for removal. I have a Tundra with a similar filter housing, no issues.
