Should You Pre Fill An Oil Filter

Dearest Tom and Ray:

I have a question most the advice you lot gave a few weeks ago. When changing the oil, you suggested filling the new oil filter with oil earlier putting it dorsum on. How do yous proceed the oil in the filter if the filter is mounted horizontally, which mine is? The former oil runs downwards your arm and drips off your elbow. -- Dooley

TOM: Nosotros recommend that y'all scroll up your sleeves first, Dooley. Actually, horizontally mounted filters are a challenge. Filters mounted upside downward are fifty-fifty more than then.

RAY: In those cases, you're really not going to accept much luck filling upwards the filters in advance. And then what you want to exercise is minimize the impairment you do during that offset
first afterwards the oil alter -- earlier the oil filter is full and the oil pressure is congenital dorsum up.

TOM: The best thing yous can practise is to ask a mechanic to show you how to disable the ignition system (depending on the motorcar, it's a fuse, a relay or a wire). That way, your
engine will "crank," but won't really start. Then you can crank it for 10 or 15 seconds, which runs the oil pump and fills up the filter, merely doesn't start the auto. That
way, the engine is running at 100 rpm during that period of depression oil pressure level instead of 1000 rpm or more.

RAY: If that's as well much problem, at the very least, don't rev the engine when you lot restart it -- revving it when the oil pressure level is low will certainly crusade unnecessary
wear and tear.

TOM: Or, although we don't recommend information technology, if you're game y'all tin can endeavor another reader's "creative" proposition.

RAY: A guy wrote to us and said that he has fiddling kids at home. He says he buys lots of disposable diapers and that every once in awhile, he comes across a defective one
-- one that's missing a stick-on tab, for instance. He takes those diapers and puts them aside for his oil changes.

TOM: He holds the filter within the dispensable diaper, fills it with oil, then turns it sideways and screws it in. And any spilled oil is captivated by the diaper, which he
then throws out. Pretty cute, huh?

RAY: I just hope he's non a practical joker, or he could get the kids' pediatrician completely worked up.
