Which Synthetic is better: Mobil1 15w50 OR Valvoline 15w40???
I just wanted to know which Synthetic oil is better? I've been using Mobil1 Synthetic but wanted to see anyone out there that has been using Valvoline?

Depends on what he wants to accomplish. As for which oil, I only use Mobil 1.

Well he lives on the east coast, so that might effect what oil he is using, when the temperature changes. I do agree though about weights of the oil being too high according to normal specs.
So because of the weights I would use the 15w40
I use the Mobil 1 Synthetic Blend 5w 30. The one that says change your oil at around 7000 miles. Then again, I live in Socal. I am actually going to try out some of the 5w20 soon.
You can do a lot of learning about this stuff at http://www.bobistheoilguy.com/
In fact there is TOO much info on that website.

Re: Which Synthetic is better: Mobil1 15w50 OR Valvoline 15w40??? (Chong)
I had a feeling everyone might say Mobil1....I mean I've been a Mobil1 user ever since I got my honda. Just wanted to see if anyone else had an opinion with Valvoline.

I work for Valvoline, so let me throw my $.02 in here.
Insofar as synthetic motor oils are concerned, Mobil1 is superior to Valvoline Synpower because they are made using different processes. I'm not going to get into the chemistry of the refining/synthesis process, but Mobil1 is a true synthetic while Synpower is not.
On the other hand, I can 100% guarantee that you won't notice a **** of a difference between the performance of the two
. See, unless you're road racing competitively with an engine that pushes super high oil pressure for extended periods of time, you don't even need synthetic. In fact, you could probably run basic dyno-bone oil for 5000 miles in your car (turbocharged, supercharged, high-comp NA, whatever) and not notice the difference.
Lots of people spend lots of money on oil they don't need. I suggest getting a semi-synth oil and running it for no more than 4000 miles between changes, personally, but if you are dead-set on a synthetic, Mobil1 is the best the industry has to offer for reasonable prices.

Re: Which Synthetic is better: Mobil1 15w50 OR Valvoline 15w40??? (Archidictus)
all the honda dealerships in the 801 use valvoline.. not saying its good or anything.. but I just figured why would honda choose valvoline over mobil1 if mobil is so good... is it cause they cut a deal with valvoline if they run there oil in there cars?

As far as using synthetic and conventional motor, I have seen the evidence. When I got the GReddy kit for my car from a buddy, he had used Mobil1 as long as he's owned the car. The oil pan was as "clean as a whistle" while my oil pan, where I used conventional 10w30, was the dark burnt brown color. I am now convenced. Mobil1 > Valvoline. Mainly b/c you don't see any Mercedes Benzes or Corvettes or BMWs with Valvoline on the oil cap, but they do have Mobil1 on most of 'em!

Re: Which Synthetic is better: Mobil1 15w50 OR Valvoline 15w40??? (EX-T)
color of parts inside a motor is based on the time inbetween oil changes, not the type of oil. however, cheaper oil breaks down quicker.
btw, mobil1 is what i use. switched from royal purple, no difference.
and to the guy who said something about the viscosity of oil being different because of where he lives..if it were a colder climate, he would want a thinner oil. thicker oil takes longer to get to operating temperature.

Exactly, synthetic oil takes longer to break down!

It can be generally said that synthetic oil is better than dino in regards to several things. One of them would be that synthetic oils generally have a much more robust additive package and higher TBN than its convention counter parts.
In the Mobil realm, Mobil 1 5w30 EP will have a much better additive pack and higher TBN than MobilClean 5000 5w30. This will allow the oil to obtain longer oil cahnge intervals. The bennifits dont stop there. Synthetic oils are made with synthetic basestocks (or Group III hydrocracked of stuff like Castrol, still techinically a syn because its 'super refined'). Syn basestocks and group oils are more resistant to shearing down and breaking down. This means a more durable oil.
But the best way to determine what oil you should use (or rather, if the oil you chose is best suited for your application), and for how long of an oil change interval, is to get used oil analysis done. This will tell you not only how your oil is performing in your engine, but also tell you how well your air filter system is (insolubles), it can tell you about possible coolant leaks (excess potassium or sodium), and whether or not your oil is severly diluted with fuel (lower flashpoint than new oil) and if the oil has thickened or sheared (the cSt at 40C and at 100C compared to new oil) .
Saying that you might not feel a difference in how say, valvoline syn would perform versus Mobil 1, that is true to the 'butt dyno' extent, but if you did an used oil analysis, you would see a clear difference.
I myself am currently using Mobil 1 10w30 Extended Performance, with a napa gold 1334 filter, i'm aiming for at least a 10k mile change interval on this, easily obtainable with the amount of freeway driving i do. Heck, the oil i had in just before this was MobilClean 7500 5w30, it had 9.5k miles on it with a napa gold 1334 filter, oil was fine, still had life in it..

Re: (chrisw85)
that is great info, can you get that done at any oil change place or is there a certain place that has to be done at?
also...i know in motorcycles you are not supposed to use synthetic oil until you hit higher miles on the engine around 50K. is this the same in car engines? though most of us are past 50K miles i was just woundering?

Re: (:Andrew)
I use Castrol 20w50 on my Civic, Mobil 1 5w30 on the RSX, and Pennzoil 10w30 on the Odyssey.
If you change your oil often enough, it doesn't really matter.

you can put synthetic in car engines as soon as you want. Corvettes come factory filled with synthetic, as do Porsches, and Vipers.
