Sup guys.

doing a new set up this year with the uberdata and such.

basically ive been running Mobil 1 10w30 for the past three years. im thinking the synthetic mobil1 is too thin for the motor. im getting a tad bit of blow by and well it needs to be fixed im wondering if simply going to a thicker oil would help the problem or fix it all together.

my question is, can i go back to a synthetic blend after being Mobil 1? im getting mixed anwsers from my searches etc. also, what weight oil is desired for a turbo honda?

 

no u should change to from 5w-30 to 10w-30 after turbo'ing anyway is what a lot of people say, i still run 5w-30 synthetic and its fine, but if u change to synthetic u need to stick with it you cant go back to normal.

 

do 3 quarts 10w-30 and 1 15-40 or whatever the next step up is. Only in the summer though.

 

i've never had blowby problems with mobil1 10-w30.

 

His motor is probably on its way out, but he can lengthen its exit by thickening the oil a little. Are you running a catch-can Mr. Vapor?

Actually it's pretty normal to have alot more blow-by on a high power turbo engine.

 

Go for some 15w50 Mobil 1 (its the red cap, or at least it used to be). You guys can say its too thick and whatnot, but honestly I think the difference in weight is neglible and barely noticable, IMO. Plus thats what all the crotch rocket guys reccomend. So I recommend it too. After all, if their motor's can wrap 2-3x higher than mine on the stuff, it should be more than safe for me to run in my car.

I didn't know he was high power?

 

to say blowby is normal could mean lots of things. its ok to have some but the more there is the more likley it is that your rings are going or you valves need to be cleaned cuz there overlapping etc. blowby is a normal wear and tear thing, not something that should be looked at lightly if its quite apparent

Well if you're turbo you hopefully have more power than stock.

Actually its fine to switch back and forth, and even mix synthetic with regular oil. As long as it has the API symbol on it its fine.

 

yes you can go back to regular oil. thats why they make the blends. it's all oil, it's compatible. if your getting to much blow by get a catch can and run a less expensive oil like a gtx or something 10-30 or 15-40.

 

well ok i guess i should clarify.

i make pretty good power....more than stock so yea. it is a turbo!

blow by, im not saying im losing power, compression is good across the board, its a b16. however some blow by with a turbo honda is to be expeted. the amount is minimal but im getting it out my (ducks) valve cover breather filter. (researching my catch can as we speak) so yea.......anywyas im aware of my issues, just looking for oil guidance.

 

just use synthetic and stick with it if your turbo

 

i was asking if it would be safe to swtich to a synthetic-BLEND

still semi-syn

I get blow-by out my valve cover breather under boost as well. Saw it on the dyno. Nothing to worry about, it's normal.

 

agreed, however a catch can should be used.

But yeah dont switch back and forth from synthetic and non, it dries out your rings.</TD></TR></TABLE>

??? please back up your statement with some legit source of infromation.. most if not all engine oils are compatible with one another this days. as long as its for your type of engine, mixing should be the least of problems.

during winter i was running shell synth 5w40. right now a mix of 5w40 and mobil 1 15w50. but going to be 15w50 very soon and i'm gonna keep that until fall. last summer i was running penzoil 15w40, its good, but not for long hwy drives, and you gotta change it more often, i haven't used 15w50 enough to figure out how often it will need to be changed.

 

You should be totally fine. Most of the information on oil that you will find is pretty inconclusive between syn and non-syn. I havent seen any solid evidence that would prove that switching from syn to non syn is bad.

With mobils new lineup

15000mi.-pure syn- $5.5X+ per quart
10000mi.-blend- $4.? per quart (just guessing on that one)
5000mi.-non syn- &lt;$2 per quart

I would rather use non synthetic and switch the oil twice as much. Instead of running 15k-mi and doing an oil change every 3-5k, I change my oil every 2k and it costs the same. Plus I ussually get free oil filters anyways.


EDIT: Go leafs! I grew up in Toronto, Ty Domi was my friends uncle

its all good if you're fine with weight selection and have not problems with oil breaking down due to heat. you won't find 5w40 or 15w50 type weights in conventional oil. 5w40 is what i chose during winter for startup and high temp protection, 15w50 is what i'm going to run this summer, and synth. is more stable than conventional, theres no way around it. i would stick wiht conventional if they offered the weights i'm looking for.

You must be running the old skool JDM rubber piston rings...
There needs to be a :rolls eyes: icon, Id use it alot on here.

 

so 15w 50 seems to be the consesus?


ot: what up muckman, hows the teg doing this year? shoot me a PM

must be something else, old skool JDM rubber piston rings are resistant due to oversized piston retainers!

 

yeah, switching from synthetic to non synthetic or mineral oil is fine. thats why they have a synthetic blend. and to answer your question, i think you will be fine with the synthetic blend if that is waht you want. personally i would opt for a thicker synthetic oil rather than using a synthetic blend with the turbo
