yea i use mobil 1 full synthetic but i noticed that my oil will burn off alot if i go into vtec. Why do you think that is? I have a healthy motor it just must be something with the make-up of their oil or something. Would going to a thicker oil help to prevent that and will it harm my motor at all because the manual says 5w30 which is pretty thin.
yeah mobil 1 synthetic tends to burn a little more than other oils for some reason. i dont know why but ive read different reasons on honda-tech but i cant remember why it was. you could switch to 10w30..but i dont think its going to make a difference in the burning. depending on where you live you can switch to 10w30. and if you have oil leaks or something then going a little thick will help. something like 5w40 or 10w40.

Murasame how many miles do you have on your motor? you should'nt be running a synthetic oil if you have high miles. you should get a high mileage motor oil. the systhetic motor oil would be to slippery for a high mileage motor. and mobil 1 is a very good oil compnay especially their synthetic oil's. but the oil tends to burn alot for some reason...especially when you hit vtec. and if you have oil leaks or burn oil, go with a little thicker motor oil.
I have 151000 km (94000 miles) on my car, so I don't think it would be a problem, but I have heard that when some people switch to synthetic oils they get leaks so I'm not sure if that would be a problem.

As for burning oil when you hit VTEC, that won't be a problem either because I don't have it. :cry: Sadly, I only have an RS.

That's a myth from the early days of synthetic oil. When it was put into older big block engines with old engine seals, the synthetic would seep through the old seals. So the rumor by the uninformed began.

yes if you have that many miles then i wouldnt swtich to synthetic, becuase you get a leak or something. if i was you i would start using high mileage motor oil.

and if you wanted to you can switch back and forth between synthetic and regular motor oil.

once you go synthetic you cant switch back

Well people don't seem to agree on some things, some of you are saying you can switch back and forth and some of you aren't. Some of you are saying I will get leaks and some of you aren't. Is anyone here a professional in the automotive industry? Because I'm really not sure what to think other than go ask a mechanic.

check the link out above ^^^^^^. some people say you can switch back and forth others say you can but they wouldnt suggest it. and others say no. so i think the answer is you can switch back...to conventional motor but it isnt goin to be as good as synthetic oil for your motor. you could do it once in a while but i wouldnt do it like every oil chance you switch back and forth.

check he link out above^^^^ if you have high miles on your motor and you want to switch to synthetic..check the it out. do a compression test & a leak down test to see if your rings and compression and everything else is good. and if your rings seem to be fine then you can switch to synthetic. but if you have bad rings then you will start to burn oil, and leak it. but there really is no point to swtich to synthetic if you have that many miles on your motor. becuase synthetic oil cleans really good and is very slippery, so it cleans all of the sludge and build up from you conventional motor oil..and it cleans that away created leaks.

I know 5,000 miles is surely past normal break in time, but I figured staying with the conventional oil won't be a bad thing, and it's less expensive in the meantime, hehe.
the main reason i would never let a motor go past 1000 for the first oil change is because while you are breaking in said motor, the piston rings have to wear into the cylinder walls, now they scrape off very small particles of metal, which drops to your oil pan below. which allows it to be sucked up into your engine. now if your filter doesnt get all of these pieces, they can get stuck in your oil galleys and cause extra wear and tear. id rather not have these pieces of metal floating around in my engine for very long. i change my oil every 2000-2500. but thats just me personally

ya my cousin got his camaro motor rebuilt. bored to a 6.3 liter. and over 8k in the motor. and he ran his car for about 45 minutes and did a oil change with sae 30. and then he drove his car 500 miles and then another oil change. and then after about 1500 miles he switched over to mobil 1 synthetic oil with mobil 1 filter. he did all of those oil changes just to get out all of the metal shavings. make sure you get a good filter the first time after you get your motor rebuilt....you want all of those shaving and things to get sucked up. and some people say to break the car in softly others say a little bit of both and same say drive the shit out of it.lol

When we fired up the engine after the build, we let it idle for over 45 minutes. Then we changed the oil. Then the next day it got air/fuel tuned on the dyno, we changed the oil again after that. Then I changed it again 2,000 miles later, then 2,000 miles after that. Did you think I haven't changed the oil since 5K miles ago in January, Evil?

use valvoline! the choice of champions such as Keichii the Drift King, Manabu Orido. etc.
I'm almost sure that they don't use valvoline at all! they are just sponsored.. Hattori sponsored by 76.. soo..
