if u want one of the best protection, id go with rotella T6.

the T6 has better protection @ 8000 miles with the mobil1 @ 3000.

go on BTOG and look at the rest results on a member's STI.


besides that fact, how many miles do u have, and do u know what kind of oil has been used.

to be realistic, there is no need to run super expensive oil like AMSOIL (very excellent oil) because in the end, you drive a CIVIC. the oils now a days are pretty close in performance and offer excellent protection. as long as you change ur oil regularly with a new filter your car will last hundreds of thousands of miles.

if u have a civic with higher than 75k miles, i would use VALVOLINE maxlife because its higher concentration of MOLY.


one last note, most the members on here dont know anything in regards to oil. they "know" only what has been told to them by a friend or word of mouth...even worst they just "speculate" and assume things about oil.

ask them what a GROUP III oil is or a PAO is and they wont know crap.

There's no such thing as "best oil" this is a subjective matter. It's more important changing it on time vs what brand or type of oil to use. Even conventional oil change at 5,000 miles will get your engine to out last the rest of your car. Go to www.bobistheoilguy.com and see for yourself.

Who cares, engines die long before oil related issues even come up. The cooling system is a weaker link than the oil system. As long as there is oil in there and it has not gone past it's life cycle you should be okay. I'm not saying use the cheapest oil you can find, because that's definitely not good. You should be okay with any reputable oil manufacturer. (I have a feeling I'm going to get flamed for this)

Just make sure you use the right viscosity for your vehicle.

I completely agree. I have never seen an oil related failure because someone pick brand A over brand B. Changing it on time is more important than the brand or type (conventional vs. syn) of oil

Yes correct, the oil is oil, only the viscosity matter, if you select a Oil of high viscosity then you mileage will drop down and the engine will be severely damaged and also you may have car starting problem as the pistons will be stuck due to the sticky oil , consider these points in mind and buy the Oil for you engine

Maybe if you're using 20w50 oil for a car that require 5w20. 5w30 or 10w30 will work fine in a Civic, but maybe get .001 mpg drop. since after time the w30 will shear down to a w20 anyways. using 5w20 has nothing to do with tighter tolerance blah blah blah in the engine. It's all about Honda and Ford etc. try to increase that gas mileage which most people hardly noticed. Keep this in mind, other parts of the world list much thicker oil for the 7th gen Civic. They don't have to meet CAFE like the US does.

Is mobil1 5w-20 synthetic or conventional? I use it and it works great

 
Rep Power: 0

Mobil 1 is always Synthetic. There's no such thing as Mobil 1 conventional.

Mobil Clean 5000 7500 are conventional.

5w30 is the way to go for our cars.

i buy what ever brand synth 5w20 is on sale.
but since i'm nearing 100k.. should i switch to Valvoline maxlife?

 
Rep Power: 0

Stay with what you have. If you switch to synethic it will actually work well, but it will work so well it will clean out all the oil build up inside your engine

Valvoline MaxLife is awesome oil As per gearbox, and if he says it's awesome, its awesome.

If the car is taken care of with oil change and other things. I highly doubt there's oil built up (sludge) on the inside.

most oils u buy on the shelf are not true synthetic oils.

here in the US, groupIII oils are allowed to be called "synthetic" even though they truly are not.

I have a 2003 honda civic and it has like 67,000 miles what oil should i use?

 
Rep Power: 313

Just use valvoline maxlife, it's all you need.

my engine has over 90k miles and ive never used synthetic, just maxlife and LC20. engine is like new inside. the maxlife does have some synthetic component (25%, moly) but its basically conventional with some good additives. and i switched to 5w30 as the engine became older, it stopped leaking oil and the vtec works better. w20 is too thin once the motor is broken in. honda only recommends it for better gas mileage (maybe 1-2mpg), not that its better for the engine. in hot climates it can actually be worse.

It doesn't matter what oil, find whatever is on sale. Any SAE rated oil will do just fine. Anything such as Pennzoil, quaker state, Valvoline etc. or even house brand such as Auto Zone, Super Tech etc will work too.

Just about all 5w30 will shear down to a w20 anyways. 5w20 is not like a w30, it will hold it's vis. overtime much better. If you think 5w20 is too thin keep in mind that 5w30 will shear down to a w20 anyways.

I don't agree that a w20 is worse in hot weather since it hold it's vis much better than a w30. I've seen many UOA that will inidate this.
