what is the best type of engine oil for a 95 civic ex d16 motor+10w-30 or 5w-30 and oil brand???

Answer 1

5w30 for sure. And for the brand I can tell you that I own 3 Pennzoil ten minute oil changes and I cant honestly say one oil is better than the other. I stock Pennzoil, Quaker state, Valvoline, Kendall, castrol and shell. As long as the oil you use is approved by the API and has the correct ratings then brand really doesn't matter. Over the last 18 years I have seen all types of cars reach 200k 300k and even 400k miles. And guess what they all use different brands. The key is maintaining your oil. Keeping it changed regularly and keeping it full. Also make sure the anti-freeze is changed on time.

Answer 2

Probably any good engine oil with API - SF and above classification will do. If your min. ambient temperature is generally very low....say around 32 degree F or 0 degree C, use a 5W 30 oil. If its higher than this , but lower than 90 degrees F use a 10W 30 oil. If the temperature is normally higher, in the region of 90 degrees f and above use a 20W 50 oil.
Good brands are Mobil, Castrol, Conoco, Shell...

Answer 3

shorty y,

in my opinion, i would say go with OE specs. unless your doing something special like raised compression or non automotive application with the engine. even then, you may read in some publications that their particular application uses a seemingly TOO low viscosity oil.
sometimes with extremely high miles, some owners choose to use a thicker oil. sometimes this works. however! a little knowledge is dangerous. you may be using an oil too thick for machined bleeds, holes, ports, and tolerances, doing more harm than good.

i know some people may go crazy over what type or brand of oil and my responses to that question.
my feeling is that if a particular oil meets the American Society of Engineers (ASE) and the American Petroleum Institute (API) requirements, its just fine for your engine. your engine may have come with conventional oil from the factory. will you benefit from using a synthetic? yes, synthetic oils are better. it is a theory no longer. but will YOU see the difference. maybe. maybe if you bought a car brand new and planned on owning it indefinately. if you plan on keeping it a few years and then maybe getting something else, whats the point of using synthetic? now if it came with synthetic id say stick with it. you wont encounter the problems we used to with the older synthetic such as smoke from the tailpipe, but like i said, its better to go with OE.


on brand names.
again some people, possibly many people will balk at my response.
if it were my car, i would use the least expensive API and SAE approved oil and conventional or synthetic depending on what it came with from the factory.
the biggest difference in brand names is the amount and types of additives they put in their oil. does it stand to reason that castrol and the 30 other brands all have their own ships, ports, refineries, and bottling????? (to mention just a few things) the same can be said about gasoline too.
i believe that private label or store brands make an excellent choice. does it stand to reason that autozone makes their own oil? theres no way they do or ever would!

remember,

*just because you use synthetic oil, doesnt mean the oil has to do any less cooling, cleaning, or lubricating. it doesnt mean it absorbs less dirt and by-products of burnt gasoline. its gets just as dirty just as quick as conventional oil. this is food for thought when it comes to deciding at what intervals you should change your motor oil. this is where i make exceptions to OE specs. same with filters.
the choice is up to you.

happy motoring!

You may want to try Amsoil, which is a synthetic oil that has great results in performance tests and is commonly used by racers. I am an Amsoil dealer and have been using it for years. I would give you my website, but I am not permitted to by the code of conduct. Just go to the main Amsoil website and search for a dealer in your area.

Answer 5

Whatever the owner's manual calls for is what you should use. Any brand marked "For Gasoline Engines" will do fine, though I personally only use synthetics -- either Mobile One or Castrol Syntech, whatever is cheaper at the moment.

Answer 6

depends on mileage and where you live, in the desert I run nothing but Castrol 20-50

ini colder parts 10-30
