Hello.
I have a new 06 mercury mariner- convience-4cyl.
First time changing oil/filter.
I purchased a PureOne oil filter part# PL10241. I just noticed that the OEM varies in size slightly compared to the PureOne. The oem is slightly longer like 3/16 .Is this ok?

Also the car has been on the lot from Jan 06. It had 20 miles on it. It was purchased a few months ago and I now have 3000 miles on it. The dealer said to service it at 5000 miles. I was doing this oil change at 3000 because I dond't think the oil was changed from day one. And a synthetic blend actually sit in the engine that long without worries. What I am trying to ask is should I wait for the 5000 miles.

Would also like to know about the filter too.

Thanks Joe

PureOne makes a spin-on, and cartridge-type oil filter for that specific car.

if your car's current filter screws on by hand, and the new one is the same, i wouldn't worry about it.

to answer your other question:


When a car has been sitting for even a few hours, it is wise to start it and pause before revving it up too much over its normal idle speed. This pause allows oil pumped up from the crankcase to flow through the galleys and cover all moving parts as they expand while reaching normal operating temperatures and proper gap tolerances. If this pause is skipped, some parts may not have adequate oil and, although it is only for a brief period during each start up, over the years engines will experience greater wear than when the pause rule is followed.
In Karl's situation where his car has not been started in several months, nearly all oil has slid off most engine parts and spilled down into the galleys and crankcase. This presents an extreme example of the preceding start up description. No car should be left unstarted for months at a time. If it has, it should be started and the pause rule described should be used.
Also important to properly maintaining cars getting little use is to allow them to run for 10 minutes or more depending upon ambient temperatures. Engines should be brought up to full operating temperatures so that they are heated enough to prevent condensation of water inside after shut off. Also, the oil will get hot enough to prevent sludge and acid build up. Always put fresh oil in an engine that will be sitting for months at a time.

in other words, YES! go ahead and change it :)
