Re: [DML] Oil filter and cross reference info

[jtrealty@xxxx]

Th subject of what oil and what filter can get pretty personal. Most 
oil companies want you to believe that their oil and their branded 
filter is best. The heart of the discussion boils down to synthetic vs 
generic. Most of the major brands are made from the same base stocks, 
the differnces are the additive packages and the bottle and of course 
the price. I would rather see someone use a cheaper oil and change it 
more often then the other way. If you calculate the price of the oil 
used for extended changes against "ordinary" oil you will see extended 
changes cost more! Over the road trucks run on extended oil schedules 
but they for the most part use oil analysis to determine oil and 
additive life. Under normal circumstances the additive package wears 
out before the oil starts to break down or the oil becomes overloaded 
with products of combustion. For most owners of Deloreans a change of 
once a year is probably less than 5,000 miles. Use a national brand of 
multi-weight oil and change the filter at every change. Synthetic oil 
is expensive overkill and unless you watch very carefuly someone could 
add something that is not compatable at a gas station! The same goes 
for DOT 5 silicone brake fluid. You lose all advantages if you mix DOT 
4 with DOT 5.(As if there are any?) If you are like most owners they 
try to do at least some maintaince like an oil change. If you figure 
the price of oil and a Purflux filter it is still cheaper if you do it 
yourself than going to a gas station. Never overfill. The best way to 
check oil is in the morning before you start the car on level ground. 
It should NEVER be over full or below add. Always dispose of used oil 
properly. With the new oil additives that are in modern oils you 
should try to avoid direct skin contact, some people are very 
sensitive to them. Wash immediatly if you do come in contact 
especially with used oil, that contains heavy metals.
