At 100,00 miles? Naw, the only advantage would come from easier cold
starts..provided you lived in an area that experiences sub-zero temps.
Otherwise, I stick to Dino. Syn might even loosen up stuf that is better
Only advantage would be to keep the engine at the state it's at now... say
you want it to easily make it to 200k.
As far as it loosening stuff up, that's right... but just change the filter
at 500 or so and again at 1500 till your first change and it'll be fine..
And use purolater or motorcraft filters
I would recommend against flushes. Do you know what it in them?
I think you are best off going strait to synthetic.
I agree with Backyard Mechanic, except that I would recommend Wix and NAPA
filters (they are the same filters, just different brands) as well.
Wix and NAPA are both made by Dana corp. and are excellent filters. I
believe that Motorcraft is also a Dana product. They care the best in my
opinion. I would rate all three the same and Purolator a close second. We
used to cut them apart with a large pipe cutter to examine the filter media,
general construction, by pass valve etc.
Motor flushes generally cause more harm than good. They loosen up carbon and
sludge then can plug the oil pump pick up screen. I'd stay away from them,
been there and screwed myself.
It should be mentioned that flushing the coolant system after years of
neglect ALSO can cause problems... the simple answer is to do periodic
specific gravity and sight/acidity tests ... or simply drain, plain water
flush, and replace coolant once every two years.
You DO NOT need to get "All the old gunk out" because there's very little of
Yes, There is one distinct advantage to using synthetic oil.
You will replace the engine sooner, before the next round of price increases
of engine rebuilds.
