Pre-filling oil filters; engine wear; idling to temperature;

[p6x]

It is a long video, almost 40';

I am not a big fan of how this guy delivers, extremely high word rate, but there are a lot of factual information, and we have had those discussions here on this forum since I have been here.

Which oil should we use in our V11, pre-filling the oil filter, the best way to get our engines to temperature.

This guy is presenting some of the answers, backed up by facts, including S.A.E. papers.

This is more four wheeled vehicle oriented. Something I got from that video though: he uses some kind of a valve to drain oil. Do you know if those exists in metric sizes?

These things are superior as long as nothing can knock them off the pan . They are used all the time on stationary equipment . e.g. power supplies , light plants , water transfer plants , etc. You don't have to fumble around R&R the drain bolt and making a mess . 

 I would use these where the drain plug is shielded very good and no chance of it being knocked off or damaged.

i’ve used the fumoto drains for years on multiple rigs, and am a fan, no complaints.  Not like its hard to remove/replace a drain plug, but its just faster and makes things easier & quicker, and not that one should live in fear of such things but it reduces/removes the chance of a cross thread, or any thoughts of whether your crush washer is fine. 

BUt also just got my new oil suction setup last week.  have an old one i’ve used on the diesel Smart (no drain plugs on the mercedes built Smart diesels), and i got used to it, but now have a compressor driven version that i’m thinking i’ll use for the volvo, to skip having to lift the front end, remove that annoying engine cover underneath, and should be able to just suck the oil out.  some debate out there about the effectiveness of that versus draining, but lots of good shops use them, and i’m not a finicky, oil worry-wart type.  (loaded statement for those who love to debate oil :->. i don’t… just like to take care of it easy as i can)

I've always been a fan of letting warm oil and gravity do its thing, but sometimes you can't.

Explain the no drain plug Smart engine again. I can't believe a drain plug can help lower the cost enough to warrant doing something this stupid . But I am not a part of the program .

Here, let me throw some cow dung onto this fire lol

Too many quick oil change racks have forgot to put in the drain plug, and discovered the problem upon starting the engine resulting in preventable warranty claims. 
Maybe that's not provable or even true, but we've all seent it.

You think that's something , you should hear stories about changing oil in a Saab 900s w/a M.T. and they drain the oil out of the trans. add 5 qts. of engine oil and the customer gets down the road and bad things happen !

All good fodder for the discussion, though I don’t know the root cause reasons Smart or others have for it all.  When I moved to LA from Alaska, among other culture shock things was the presence of quicky oil change places that would change your oil and filter for the same or even less than i could buy just the oil.  What?  So I did that thinking how nifty that was, but always a bit suspect, then sure enough one day I went to drain my own oil for some reason and found the drain plug was badly cross-threaded.  well, was fun while it lasted.

That little Smart diesel engine, basically what I’d call a golf cart with 57hp, is all mercedes built and has been a solid little bugger since 2006, no-drain-plug-and-all.  Plastic outer body never rusts, frame is some kind of space age alloy engineered to handle some nasty crash scenarios (check out what some British university did for testing, published video on YouTube), and the drivers side has more head and leg room than about any rig i’ve had my 6’4” frame in.  But it’s still basically just a golf cart you get to drive 60mph on the road.  But we digress!   Sucking oil out is not new to me, because of the Smart, but only recently have I looked more into doing it for other rigs, hence the foray into messing with it using a better suction device.  The Super Duty diesel (“Whitey”) that holds 12+ qts will still be drained by a quick scoot underneath on the creeper, a short twist of the fumoto drain valve, and voila, 12+ qts drained.  Not nearly so quick for the Volvo, low to the ground and with an engine cover underneath… a real hassle on a comparative basis.

I am a member of a mechanic's forum and a few years ago a member was overhearing two managers of fast lube service joints talking and one was bragging about how his store was under the target of incidents per/1000 service jobs . Wow ! I wonder how the 101st Airborne feels about a 95% success rate on parachute packing ?
