Hello;

Just had my 2000 accord with 4cyl in for tis 30k mile service per owners
manual.

Dealer may have used 5/20 instead of 5/30, can this cause any harm to the
engine

All Honda engines are using 5W20 now, even retroactively back to at least
the 2000 MY.

The 5/30 is thicker at higher temperatures (summer time) while the 5/20 is
thinner at the same higher temperatures. At lower temperatures they are the
same. The oil is multigrade.

Just remember that the thicker the oil the more resistance it causes the
engine parts. But if it is too thin it's hard for it to stick to the parts
that need to be lubricated since it will flow like water, especially at
higher temperatures. 5/20 is a measurement of thickness/thiness (viscosity)
at both lower (5) and higher(20,30) temperatures.

Unless the engine is of very high performance then 5/20 and 5/30 might have
different results on the performance. For the average honda, 5/20 and 5/30
don't make too much difference. Of course it depends much on the weather as
well. If you're in Alaska you'd use different oil than if you are in
Florida.

Take a look at the lubricants mfr Web sites for advice. www.mobil1.com
recommends using 10W/30 above 14F and 5W/30 below 95F. They also recommend
5W/20 (substituting their 0W/20) for the 2001 model and the specs on the
engine have not changed so they are following Honda's advice... for obvious
reasons. I tend to think Honda has approved the 5W/20 for your car because
the dealers do not want to carry special grades and 5W/20 is what they need
to satisfy Honda reqts for the newer cars. Personally I would not want the
stuff in my cars, even the new models and especially if temps get >90F.

5/20 oil will not NOT cause any harm to the engine. Honda mechanics now in
most cases use 5/20 oil instead of 5/30 oil since the experts at the Honda
factory in Japan determined from their research that 5/20 oil works better
than 5/30 oil. I was told this by the service manager at the local Honda
dealership.

I picked up a Honda lubrication brochure while I was waiting for
service on my 03 Accord. My recollection is that it shows 5W20 only
for the 03-04.
