Hi all Sifus!

I just want to know which engine oil that you guys recommend for the 4G63T (evo2/evo3). Is 20/50W good enough? (I mean to reduce the 4G teppet sound.)

I apologize if this has been mentioned previously by the fellow zth members. Seriously need some advise, thank you very much.

regards.

when ur hydraulic lifter (Lash) worn out already.. the only way to prevent sound is by using thicker engine oil... but if ur engine is in perfect running condition lets say just after overhaul... 10/40 would be nice... but if u require higher oil pressure (for modded cars) 15/50 or 15/60 would be better....

i am quoting the range from Motul 300V category... different brand might have different vicosity though its in the same category...

personaly i like the Motul 300V 20/60 (ester base) but i am not sure is it too thick for 4G but i was using the 300V 15/60 for my 4G93T last time...

the numbers on the front rating is for cold start... so in malaysia we don't have winter.. so to look at the vicosity just look at the figure behind...

All sifus!

Well, for myself, Castrol Magnetec 10/40 should be good enough as most of us change the engine oil every 3000-4000km (I assume :D ), it will cost a bomb if I use those full-synch oil and change every 3000km...


Anyway, thank you very much for sharing with me on this engine oil thingy, I learn a lot. :)

 

[ekinomae]

share share..

mine like tony tony also mazda b8. Use Motul 4100. Change every 5k km. Never try using oil addictives though. Dun have those teppets sounds.

 

[racing temptation]

In a hot climate like ous the best engine oil recommended by drivers like Karamjit

Singh is a 15/50 semi or mineral engine oil for any car - semi..Motul 15/50 4100,

mineral -Toyota motor oil 15/50 and u wont go wrong. How can u argue with a

world class rally driver who deals with high revving...so try it and save ur engine.

gearbox oil- nothing but the best...Red Line or motul.

try it and ull feel the difference.

for rotary engines- Castrol RS 10/60.

Happy accelerating brothers and sisters.

im using hks 10w-40 ....dunno why tappet sound increased than b4....but previously using AMOIL thicker treament forgot the grade d,not so obvious tat time..izzit my engine not suitable with thinner grade lidat ?

 

[GT_AUTO]

bro,i don't like to be the 1 to blame hks as i love their product.since u mention
that the hks oil is 10w-40,i assume that the oil u bought is semi syn.try n look
at the API grade on the oil.it's SJ grade bro.it's an old grade oil.this grade
is not suitable for modern engine already.if i'm not mistaken,this grade was
first introduce back in the late 90's.maybe cos of profit or what ever,they
bring in this oil n sell to us.since it's hks,ppl who use it start bragging about
how good this oil is but in fact,it's an old grade oil.hks don't produce this
oil long time ago.i don't know where they got the stock from but i think
it's an old stock.just my 2 cent.

 

[zero2hundred]

icic bro....but u said not suit for modern engine, but my e2 engine consider old technology er??

 

[clockwork]

Redline 10w30 full synthetic,can it be use on 4G63T old engine?

 

[MitonCT26]

4G63 has been around for at least 18 years and still going up to evo 8... it's old technology la for sure hehe...

as for my old beat-up-slow-and-noisy junk i've been running Castrol RS 10w-60 since it's rebuilt till now. my personal opinion is that mitsubishi hydraulic lifters are quite picky on what oil you feed them. Tried some other oils but most of the time the lifters will make noise somewhere around 2500kms of usage even for fully synthetic. new ones cost about 160 each if i'm not mistaken so times 16 pieces...you do the math. if you feed all types of oil and it makes noise even from the first 100kms...it's imperative that you should replace it...

on one hand if you're on a tight budget it's a good reminder wat...once noisy change engine oil...hahahaha...

10w-30 is abit too thin in my opinion even if you just rebuild your engine. plus the fact that it's a turbo engine means the positive pressure from our combustion chamber will evaporate most of it... er... correct me if i'm wrong...my tech very china mali bawah pokok one.. hehehe

 

[zero2hundred]

lifters sound izzit sumthing like tappets sound? just the sound bigger rite ?

 

[GT_AUTO]

icic bro....but u said not suit for modern engine, but my e2 engine consider old technology er??

i doesn't matter whether ur engine tech is hi or low.the better the oil,the
better the protection.

 

[MitonCT26]

lifters, tappets, bullets, whatever term it is...we are referring to the same thing actually.

tonytony update,
here's the story. from mineral 20/50 i switched to semi 10/40 Q8 for 1 oil change. very good for the 1st 3000km, then the tak tak tak tak tik tik tik sound came back. so, then i saw motul 10/40 semi 4100. wow, expensive...but what the heck, try lor. very good oil.......smooth like no tomorrow. no sound till the 3000km again. so decided since motul so nice, change another round. not good results. from 0km onwards.....all got sound.
headache already, ok, so i heard from fellow forummer Batousai tht the only oil that works for lash adjusters is Mobil 5/50 full syn. ok lor....bite the wallet 1 last time to try. WOW !!!! really very very very good........smooth, revvy, QUITE...no tapping at all !!!! not until the 5000km stage ler. made no mistakes about it, this oil is top of the range ...retailing about RM210 for 4L. very expensive stuff. downside is, after the 5000km range, my oil begun disappearing. somehow engine makan minyak ler...so sad.
now with syntium 15/50 full syn. not so good. tappet sound still there.....but what to do no money.
for those who wanna try mobil 1, go to zhapalang.com.my. that guy there selling mobil1 for i think RM180. still expensive, but cheaper than mobil stations ler. alternatively, i also heard that carrefour seling at RM140 for 4L.
those who are already on full syn, no harm trying mobil 1. sure no regrets for you and your tappets.

 

[tonytony]

btw, i do think that the cold start number in the beginning X/50 does playa role in the performance of the oil in our engines, even in our hot country. next i wanna try is a 5/40 grade ful syn. why ? coz i found that when i used a /40 semi grade last time the tappets were alot better for awhile. 5/x grade is better than 15/x grades actually. the reason ??? tappets need the extra oompph during cold temp conditions.
u notice that an oil range of 5/50 is way more expensive than 15/50. the reason is because the 5/50 range can withstand a wider temperature diff than the 15/50. and thus, the quality must be better.

 

[tonytony]

bro Miton,

i haven't tried the X/60 range oils before. is it ok so far ? coz it looks like its too heavy oil for the tappets ???

 

[MitonCT26]

Tony ;

very spot on comments about your experience.

I have been using this since my engine rebuilt a year ago and 15,000kms later, have no regrets. maybe it's because the nature of my driving style or maybe because of the engine configuration, the engine oil runs sweetly with the engine oil. as sometimes i travel extensively all around malaysia, i only change engine oil every 8,000kms. hehehe... serious! just that every 4,000kms i change the oil filter and top up with the same engine oil.

too thick? i do not think so as it would only tap once a while, but maybe it's the cams...

 

[tonytony]

bro Miton,

good to hear that uve found a good oil for your ride.

anybodi else have got good experience with Q8 full syn ???

 

[tonytony]

some updates for all bros...
from petronas syntium 15-50 full syn, i've now changed to Bardahl 5-40 full syn. only 1st day using the oil but what i can say now is, very good :). tappets are 80% better and best of all its so cheap @ RM75/4L !
got it from Zenden from Zhapalang.com
