dear bros...

 

i just changed to 5w20 oil (previously on 5w40) and hv run 300km.

somehow, now i experienced at expressway speeds 80-90kmh, the car is difficult to maintain speed (like not responsive, hv to step harder to maintain speed, compared to last time)...is this normal for a thinner oil?

 

can bros on same weight oil share?? thank you thank you.

[Heartbroken]

im using 5w20 on my getz for sometime no diff except for slightly louder engine noise... but got a improvement in fc

I'm using 20wt oil on my 7yr old City (180k km mileage) for the past 4-5yr, no problem of these sort. In fact, i could push above 180+ km/hr in NSH when i visit my relative there. Now avg 14km/L.

Give some time for the engine to adjust the new oil weight.

imo, avoid red-lining or prolonging high rpm if u use a very thin oil like 20wt, cos it may thin out further, rendering little or not enough protection to the engine

for me, i use a grade thicker than the minimum recommended weight..

 

and u have gone over 180kmh on a city? salute u bro

i drove once some years back.. steering very light even at low speeds..

0W20 user here, this oil weight is also recommended my owner's manual and my UOA results are excellent.

 

FC improved and car feels a tad more responsive at low revs as compared to agent's mineral 20W50.

 

What is the age and make of your vehicle? Could it be psychological?

The >180km/hr thing is to test top speed and clear carbon. Just a sprint after the toll and not sustain speed. Anyway at >160km/hr, my City feel like flying liao... hahaha

hi bro..im driving a 2yo lancer (cs3) with 30k mileage...

dunno lei....im beginning to feel more and more its not psychological...now im almost 400km on it alr...stil dun feel better abt his highway speed...

 

do u feel responsive on expressway speeds?

wat oil? some organic based ester hv been known to display dips in viscousity. this will result in poor oil pressure. possibly this is wat u hv experienced.

 

but then again, it may b ur crankcase not suitable for this range of oil.

hey bro i seriously suspect so...i really feel the sluggish at 80-90kmh...i hv to step harder...

i am using Mobil 1 Extended Perf....is it belonging to the type above? thanks bro

[Maroon5]

hey terence dunno if u rem me, i was the white lancer who bought fr u...

dunno lei...mayb this oil weight not suited for my car???

[Maroon5]

hi bro...my experience (400km) on this oil...is quite silent the engine...in fact no diff from my previous 5w40, in terms of idling n cold starts (i was stil thinking mayb i hv to warm up longer in the mornings w this oil but no such issue)....only complaint is the lag at expressway speeds...

[Maroon5]

thanks bro...ya wil do so...waste of money to change so soon la...

[Apollo]

nope, that one fully synthetic.

 

u on open pod si boh?

 

simi Apexi or HKS?

[Trex101]

Check your oil level, see if it's overfill. Overfill oil will cause increase drag by the engine moving components.

[Maroon5]

haha no im jus using those stainless steel drop-in....

[Maroon5]

not overfilled bro....exactly 3 qt...middle of my dipstick...

[Bentwy]

i'm on a wt20 oil too. no regrets.

i don't even notice a change in engine 'roughness'.

i find the revving even better with thinner oils - but i'm not a cheongster.

 

at what speeds/rpm do you feel the sluggishness?
