so what Synthetic oil to use?

[Sworkhard]

Not at all.  You can go to synthetic and back to regular or mix the two or whatever.

is it true that once you go to a synthetic oil, you can't go back to a regular oil?

castro syntec edge works great for me

5w-20 Castrol GTX every 3500 miles.

This thread is a good example of the range of intelligence across the forum. Some people have good information to share and they should be praised for it. Others are just wasting space and helping me wear out the scroll wheel on my mouse.
Anyway, this makes me want to research a lot more about oil and maybe I'll be able to find the truth behind all the bs.

For those who use Mobil 1 Advance Auto is having a sale til 6/24 on M1 Extended performance synthetic and M1 filter for $23.99 I believe.

would you guys recommend m1 filter when using mobil 1 5w-20? i used an oem filter...

Honestly, it does not matter.

I've used both of these filters...both are quite good...the M1 can probably go a bit longer (7k miles)...but the OEM ones are about 1/2 the price and 90% as good.

I have always heard that Fram makes the Honda filter, so I dont use it.

what do you all think about Royal Purple motor oil?  i've been using it and i like it, but don't know if i can justify buying it for so much.

i heard its not as good. it doesnt last long,

Not true at all.  Take a look at this oil analysis for a 2007 accord. The guy ran royal purple for 12k miles and it did very well.  You guys need to stop repeating things you hear, and back up your claims with evidence.

I just changed mine from Mobil 1 5W20 full synthetic to Valvoline SynPower 5W20 full synthetic. I heard Valvoline is kick ass stuff

Synpower is indeed a good oil. This guy ran it for 9k miles in his accord and all of the wear parameters came back great.

I've been doing a lot of reading about oils lately.  Honda builds great engines that wear VERY slowly.  You can put almost any oil in a Honda engine and it will wear very well.  I've seen reports of people running conventional motorcraft 5w-20 in a Honda engine for 8K miles and the results come back above average.

royal purple is that shit. i use all royal purple products and have never been disappointed, the only thing is its about 50$ for an oil change doing it yourself.

i would not run that for 8K


ran my amsoil 0W-30 full synthetic and full synthetic filter for 9K and test results came back ok but they said not to use it for more then 7k based on results

I forgot to mention that oil break-down is very dependent on the following things:

-Environmental conditions (hot vs. cold)
-Driving style
-Average trip duration (long vs. short)
-Highway vs. city miles

Because of these variables, the usable life of motor oil will vary from vehicle to vehicle running the same oil, in the same engine.  The only way to determine the max life of your oil is to have a sample tested.  Synthetic oils are designed to last much longer than a conventional oil.  Changing synthetic oil at 3k miles is like replacing your tires with 50% tread left....dont waste your money.

Here's some questions.  I usually always run Mobil 1 5w-20 full synthetic.  But, everytime I buy my batch I get torn between trying their semi-new "gas saving" 0w-20 brand, or their extended performance 5w-20 brand.  I already kind of understand the possible benefits of 5w-30 in our cars, but does anyone have a factual say when it comes to the different choices that Mobil 1 offers?

^ Anyone?
