At our company's fleet garage, we bought "bulk" oil, but it came
packaged in 55 gallon drums. It was never delivered in a tank truck
and pumped into an open bulk tank.
This level of "bulk" was substantially cheaper than buying bottled oil,
and the risk of contamination was less.
distributor, but then they decided they didn't want to handle barrels
anymore at they put in bulk tanks with metered pumps - made it a lot
wasier than pumping from a barrel into a pouring can - no more funnels
required - and less, not more, possibility of contamination because
there were no extra containers or stages of handling involved.
The only problem is you NEVER really knew what you were getting. They
handled Valvoline, Castrol, Quaker State, and at least 2 other brands
- all of which made good oils - and also cheap oils. Which grade
were we getting this month? from which company?.
The article linked above is also a helpful read. I noticed the part
that says "Depending on driving conditions, we expect oil change
intervals could be approximately:
Up to 10,000 miles Normal commuting with highway driving
5000 to 7500 miles Trailer tow/high load driving
3000 to 5000 miles Short trip usage, extreme cold or hot
The fact that two very different different car manufacturers (Honda
and Ford) are saying a 10k mile interval is fine for many speaks
And with short trips in cold weather a synthetic oil does not buy you
much in extended oil life. SOME, yes. But not a lot. In high
temperature (extreme heat) synthetic DOES buy you a fair return in
extended oil life.
"End of story" is a good epitaph for this rather useless thread. This
subject has been argued on this and other newsgroups for years.
You take the point that some are foolish because they dont subscribe
to your ideas about lubricants, maintenance intervals, etc.
You havent proved any points. You just keep talking, saying the
same old things, never with an iota of data.
It is boring.
