Oil pressure emergency

I'm impressed by all of that. This is excellent information to keep on hand.

BTW you should fill the filter with oil prior to installing it.

Never prefilled the filter and never had a problem. I don't ever recall hearing that as being recommended. In fact, I think I recall the Guru saying that it was not necessary.

There's alot of things that aren't necessary, but filling the filter definitly doesn't hurt, especially on an engine that has to have a TSB for an oil pressure problem after an oil change.

[codewize]

Right, what it does is allows almost immediate circulation of lubricant to the engine where as an empty filter will fill with oil before the engine ever gets any.

Thus every time you change you're oil with an empty filter you're starting and running you're engine with no oil for a few seconds while the filter fills up. If you had a oil pressure gauge you'd see it sit at zero for a few seconds, literally 5 or so.

I'm not sure who the Guru was but I was taught that when I was 10 and I've done it ever since. It only makes sense.

The Guru was a GM powertrain engineer who used to post here.

I always wondered that. What happened to him / her?

He pretty much just disappeared. I think the General was involved in some way.

We used to pre-fill the filters on turbo engines, to make sure the turbo bearings didn't starve for oil, it's not a bad idea but not required either.

If every engine rebuilder and hot rod magazine on earth recommends, orders, you to pressurize and lube a rebuilt engine prior to lightoff, why would you not prefill an oil filter, especially when the process on a N* is so ridiculously simple? I have never used a "quick lube" service, but often wonder why they don't blow an engine a day due to dry starts. (Shows you how good modern oils are...)

Since the oil filter is vertical, I always prefill it. I can't imagine trying that on some of the horizontal/angled ones, but when they make it easy....
