Dealer Switched from Castrol to Mobil Oil - Downgrade?
My local Honda dealer, where I get my oil changed, switched from Castrol to
Mobil oil. Also, the paperwork and windshield sticker no longer indicate
the grade or weight (should be API service SJ "energy conserving" oil, SAE
5-30 viscosity, for my particular year and model).
I had an impression from years ago that Castrol was considered a superior
brand. Is that still true, and if so, why?
The service manager at Mel Rapton Honda in Sacramento, CA, says one reason
he switched is price. Mobil is cheaper. And he assures me it meets all the
factory specs, although I can't verify that because I can't see the label
for what they put in my car.
He also says that all Hondas come with Mobil oil in the crankcase from the
factory, whether in the US or Japan. Is that true?
OK, so Mobil is cheaper. Assuming the product is marked as meeting the
factory specs for my car, is it good enough?
I am not asking here about synthetic oil; please limit responses to
conventional oil products only.
And please, I hope to hear informed and expert knowledge here, not
speculation and guesses. Thank you.

speculation and guesses are what you will get. you are not paying for
this advice directly. of course, it can be argued that you are paying
for electricity to power the computer, the purchase price of the
computer, the internet connection, etc...
there is nothing wrong with mobil. you are silly if you think
otherwise. clean, fresh oil of the proper (as per the particular
vehicle manual) viscosity is all you need and all you need to worry
about.

Re: Dealer Switched from Castrol to Mobil Oil - Downgrade?
OK, zee, thank you. If my dealer is using "Mobil Clean" then according to
the Mobil web site it does meet the owner's manual specs for my car. Not
only as to viscosity, but also as to API service rating SJ and "energy
conserving" in my case.

Re: Dealer Switched from Castrol to Mobil Oil - Downgrade?
Here in the southeast Mobil is the distributor for Honda motor oil. I'm not
sure about the rest of the country. The Honda branded oil is formulated by
Mobil to Honda specs. There's not much better for your car. As for Castrol,
it's a fine motor oil. Probably no better or worse than any other major
motor oil manufacturer, except for some of the premium and/or racing oils or
synthetics.
What Castrol is best for is marketing. There is no oil company that spends
more time and money on marketing and promoting its product than Castrol.
They spend millions on promoting and the result is what many people
including yourself think that it is better and consequently it pays them
back in sales. Maybe it is, maybe it isn't better. But there is not much
difference between equivalent spec Mobil or Castrol or most other major
brands for that matter.
If you want superior, use Amsoil or Royal Purple, but be prepared to pay a
handsome price for something that will make little or no difference in a
well maintained properly oil changed vehicle.

If you follow an average oil change interval, any API spec oil is just fine.
All modern oils are essentially good and better than they used to be.

not "any" oil. motorcraft api spec "semi-synthetic" makes the seals on
my 89 civic leak like sieves. subsequently running castrol or mobil
oil, i've had no leakage problems from the same seals whatsoever.
first line oil analysis is spark spectrometry. [quick and cheap.]
that's good for inorganic components like zinc, but useless for organic
component analysis. on spark analysis, motorcraft oil appears to have
an inorganic additive package just as good as other oils. but if it's
causing leakage, clearly it's missing organic components like seal
conditioners - and this would never show on spectrometry. guess that's
why it's cheap.

not "any" oil. motorcraft api spec "semi-synthetic" makes the seals on
my 89 civic leak like sieves. subsequently running castrol or mobil
oil, i've had no leakage problems from the same seals whatsoever.
first line oil analysis is spark spectrometry. [quick and cheap.]
that's good for inorganic components like zinc, but useless for organic
component analysis. on spark analysis, motorcraft oil appears to have
an inorganic additive package just as good as other oils. but if it's
causing leakage, clearly it's missing organic components like seal
conditioners - and this would never show on spectrometry. guess that's
why it's cheap.
