how much oil it is reducing
Only STDs rings will not help in symptoms it will improve the oil consumption but will decrease the economy and acceleration as well
Well brother, take my words, I have been through same, 0w20 should be used from start, I suggest, sell yours car, there no proper solution in Pak.
FYI, oil rings has harden.
@Nabeel_AliSame was problem with me. 2013 vitz 80k odo... I was using 10w30 Toyota patron plus...it used to consume 1L with 5000km... I needed to add up oil. Last time I switched to 5w50 Toyota and to my surprise oil reduction is reduced to roughly 1 glass
W.S. Brother I think switching to thick engine oil grade will just camoflauge the oil reduction issue, but will not eradicate it completely.
Mind sharing the details about 5w-30 fully synthetic engine oils which had been deployed; like brand names, API / ILSAC rating, surety that oil is 100% genuine and original, etc.?
If everything has been done properly and all things have been timely taken care of, then this should not start happeing that early. 74,000 Kms is too early.
I would sincerely suggest having your car's engine thoroughly checked for any / all issues, provided engine oils deployed had been 100% genuine and original.
stuck oil rings or hardened ones can benefit from thinner oil like 0w20. they got hardened or stuck because thicker oil never made its ways in between and over the period of time the rings got stuck. Hypothetically thinner oil may help in getting the stuck rings back to normal as it can penetrate in between where the thicker oil was not able to reach.Before selling car or rebuilding why not try 0w20.
5w-30 is not able to do this job instead of 0w-20?
I agree with you but if heavy sludge is accumulated in stock oil control rings then it can't be helped out in case of 1kr factory oil control ring design. But in other engines if sludge is accumulated in between the oil control rings using low viscosity oil does help to restore the efficiency
Asalam o alikum
Very informative vitz group. Anyone please guide me, in may 1.6 altis i was using taglon 5w-50 but now im switched to total quartz 9000 5w-30 and i felt improvement in drive, engine is felt more smooth (my personal observation). Now my vitz 2011/2014 88k km driven with healthy engine, using miking 10w-40. Now im planning to switch on total quartz 5w-30. Should i go for it or stick to what im using right now. Seniors kind suggestions would be appreciated.
If engine is healthy you can go for 0w20 as that's the Toyota recommendation.
5w30 is also OK.
I would suggest Total Quartz 9000 Future Series 5w-30, provided engine health is perfect and you are not facing any oil reduction issues.
Yeah compression test must be done...though i see no sign of smoke and decrease in acceleration even fuel average is same.
well not sure enough but according to dipstick its around 40%
yeah thats what I was thinking... but I used good quality 5w30 fully synthetic oils wasnt expecting this. And I had second gen vitz as well it started to decrease oil around 130k kms mark... dont know why its too early on 3rd gen vitz
Bro I didnt want to shift to 10w40 but this time oil decreased drastically.... I used total 5w30 and now shifted to LM 10W40
thats the thing i dont understand ... I have used genuine air/oil filters and many times also poured hi octane. Maybe its the issue in Pre Fl vitz and I think they sorted out in facelift one with newer engine
good luck with 10-40 if you still not see any improvement then you may try toyota new taglon 5w-30 and then 5w-50
Well thank you for advice. Honestly speaking i never check the oil gauge for reduction. I never used genuine oil and air filter, im also planning to try genuine oil and air filter because i have observed vibration is increased and feel sluggish. Cat is also one of the reason.
