Best Brand of Oil

I know I may start a small-scale war here since a lot of times
preferences for brands of oil differ from person to person, but I still
thought I'd get a "vote".

I have a 1990 Honda Prelude that I recently dropped in a JDM B20A. (Had
to replace my B21A1 because it was burning 4 quarts of oil per week)
The B20A has about 50K miles on it, and it's running great. (It's only
burned about 3/4 of a quart in over 2,500 miles, and most of that is
probably my fault since I'm an aggressive driver) The time for an oil
change is drawing near, and although I know the correct weight is 5w-30,
any suggestions on the best brand/type? I've always heard Castrol GTX
is good, but others swear by synthetic. I don't know what brand the
mechanic that installed the engine used, and frankly, I don't care, as
long as I'm using an oil that will prolong the life of this engine. As
far as weather goes, I live in the piedmont of NC, so our average
summertime temperature is upper-80s to lower-90s. (Don't know if that
matters or not, but figured I'd mention it anyway)

One final question: The B20A's horsepower peaks at 5800RPM, so when I'm
shifting, that's usually what I rev it up to. Is this going to hurt the
engine even though the redline is at 6500 and I NEVER rev it that high?

Thanks in advance!

Hi Jon: I think if you stick with any good name brand you cant go
wrong.BUT having said THAT >? when you operate machimnery at or near
its potential constantly, it doesnt matter what brand of oil you use .
it will break down and wear out quickly.
Speed kills in more ways than one .

Having said that, THOUGH IF I WAS REVING MY CAR ENGINE NEAR ITS UPPER
LIMIT MOST OF THE TIME ?I WOULD OPT FOR A 10 W 30 OR 15W 40 DEISEL
RATED OIL.

Deisel rated oil has more anti-wear phosphorous in it than regular
auto oil.

Of course with those few miles on the engine I would suggest 15w50
Mobil 1 synthetic , as far as I know ?; the best motor oil on the
market today as many high performance cars come filled with Mobil 1
from the Factory including Porsche , Dodge Viper Mercedes-Benz etc..

There MAY be a SMALL chance of developing some leaks with synthetic on
an engine that has 50,000 miles on it but its cheaper than a another
engine to repair if it happens

I had a Honda Accord with75,000 miles on it when I swtiched to Mobil 1
and never had any leaks

I personally use Mobil 1,5w30 in my `02 Camry-4 but it only had 45,000
miles on it when I bought it, so far no leaks and it starts in the
wnter every time .

I know you`re in the sunny south , but up here synthetic in Ontario is
almost mandatory in winter .

Mobil 1 does not even begin to thicken until the temp reachers -47 *
F(according to the label) and I can vouch for this as my car starts
like it is summer every day in the winter.

I also use Mobil 1 15w 50 in my `01 750 Honda Shadow and the
difference is amazing compared to dino oil .
shifts are smoother and neutral is a snap to find.

Synthetic by its nature is MUCH slipprier than dino is the reason why.

I used to use dino oil in all my vehicles but since Mobil 1 came out ?
thats all I use now

Of course the only time I get near to the upper rev limits is when I
drop the car into passing gear but this is not on a daily basis and is
infrequent at best.

Hope this helps ?
