I don't claim to be an authority on this, but I have never EVER heard of an
oil causing an engine to be damaged. Yes, I'm sure that if you put
vegetable oil in the result would be...not good. Also if you used gear oil
there might be some pretty bad problems. If you have any doubts, look in
your owner's manual. It should give you a chart that shows you what oil to
use for what temperature ranges. Today's cars (in general) use a lighter
oil, so 30 weight ought to be fine.
Also I found this on the web at
http://www.vtr.org/maintain/oil-overview.html:
"Multi viscosity oils are one of the great improvements in oils, but they
should be chosen wisely. Always use a multi grade with the narrowest span of
viscosity that is
appropriate for the temperatures you are going to encounter. In the winter
base your decision on the lowest temperature you will encounter, in the
summer, the highest
temperature you expect. The polymers can shear and burn forming deposits
that can cause ring sticking and other problems. 10W-40 and 5W-30 require a
lot of
polymers (synthetics excluded) to achieve that range. This has caused
problems in diesel engines, but fewer polymers are better for all engines.
The wide viscosity
range oils, in general, are more prone to viscosity and thermal breakdown
due to the high polymer content. It is the oil that lubricates, not the
additives. Oils that can do
their job with the fewest additives are the best."
If this is to be believed, 10W-30 is a much "safer" oil than 15W-50.
Hope this helps.

Are you completely sure, I have been using 15W50 by 3 years?
Many people here told me if I do that I will crash the engine?
