Oil Filters May Make a Difference

[Chuck]

Just got back from having the Honda dealer change my oil and filter. Had a Fram oil filter, since Insight parts are not very common. A guy there explained that the Honda filters are designed to get oil pressure up almost instantly - not the 10-15 seconds conventional filters take. This reduces wear and tear on the pistions, crankshaft, etc.

This is critical info for all who FAS and P&G.

What I'll do is drive the car 10 seconds before cutting the engine to make sure the oil circulates.

I'll still do P&G, but there may be times I'll feather the accelerator instead.

AFAIK getting oil pressure up has absolutely nothing to do with the filter.

The oil pump pulls directly from the bottom of the oil pan and the oil has to travel to the top of the engine and then fall back down through the components. I think this means that viscosity and temperature are the two keys to making the oil flow early.

One reason that synthetics and/or some additives (like Lucas Oil Treatment) are so popular is that they leave a coating on the various engine components where normal oil all drains off into the pan. This means that when you do a cold start there is already some lubrication in place vs. running "dry" until your cold oil makes its way there from the oil pan.

I have never before heard of a filter manufacturer claiming that their product delivers oil faster. Even K&N - a performance-oriented company - simply says their filter helps protect high-performance engines with better filtration - not some oil-to-the-parts miracle.

As long as the oil filter has a decent anti drainback valve, there should be no delay in getting oil pressure up. If the oil filter is installed vertically, no anti drainback valve is required.

I don't know about the Insight, but the Camry Hybrid oil filter is vertically mounted - no anti drainback valve needed as gravity keeps it full.

FYI - K&N states the following about anti drainback valves:

K&N PERFORMANCE GOLD OIL FILTER

* Anti-drainback valve (where applicable) eliminates dry starts, prevents oil from draining back into crankcase during engine shutdown

I think the Honda guy was talking about the anti-drainback valve.

The Insight and CRX oil filters are horizontal.

We Volvo buffs have long known that the those cars' OEM Mann filters are far superior to the Fram, for exactly the same reason: the Fram has an inferior or missing anti-drainback valve. The low-oil-pressure light remains on for several seconds while the filter is refilled.

With the OEM/Mann filter the light goes out as soon as the engine catches.

Hi Brucepick:

___One of the best ADBV’s in the business comes from Champion Lab’s, makers of the Walmart SuperTech, STP, Bosch and Mobil1 oil filters.

I'll be watching how quickly the oil gage light cuts off cranking the car.

I use nothing but, M1 or PureOne oil filters....

I use Wix, all the filter analyses i've seen on the net give them an excellent rating among the standard budget brands.
