Switching from Shell Helix HX5 10-40 to HX3 20-50

[pwuser150469741418]

Han yaar aisa hi lag raha hai talked with my mechanics brother who is also a mechanic and he does compression test. He also insisted 20W50 daalo or mazay se chalao kam nahi karegi oil gaari. Btw that overhaul thing was a joke. I know my car doesn't needs one. At worst it would require valve seals to be replace but thats also very unlikely at this moment I believe.

Bhai koi khas farak nae parne 20 w50 se meri gare ka emgine bhi weak tha jaha 1000km ma wo 1 litee 10 40 kam kr re the 20 50ma 1000kms ma 800 to 900ml kam kr re the... Ap sab se pehla leakages tu band krwaye distributer ki tu rings wale seals hoti hain wo 10 min ma change ho jati hain our baki jab gare fully heated ho tu 5 sec kay leya neutral ma. Full accelrator de kr check kre kay gare smoke de re hai kay nahi our phir yaha a kr bataye...

Always buy oil from Shell Pump because they are always original. These shops sometimes keep fake oils which also produce smoke. Also check your PCV valve

If your oil is fake and is producing smoke then when you will chnage to genuine it stop smoking after few KMS drive.

My car model is 2001cultus carby and i have been using shell oil from F6 islamabad from tthe past 15 years recently when i changed my engine assembly i opted for havoline this time and in my next oil change i will go for zic x7000 which i will buy from zicoil.Pk
Just wanted to say it doesnt makes a lot of difference in oil consumption while going from 10w40 to 20w50 shell it will just make engine more heavier especially in winters so its better for you to stick with 10w40 shell and keep filling it up during the journey if your car doesnt smoke on full throttle then it will not consume too much oil.

Distributor ring seal already fixed bro the day I made this thread. I think you didn't get what I was saying.

Mera kehna hai k oil jo dipstick per kam hua hai wo oil leakage ki waja se hua hai. Mera mechanic keh raha hai nahi gaari oil burn karna shuru hogai hai is liye 20w50 use karo.

But I will just buy a 4 litre Shell 10w40 and top it up to full I think it will use up around 300-400ML. and keep the rest of the oil for next change.

[pwuser150469741418]

Yup mine is 2002. I buy oil from a very trusted source so I am confident the oil isn't the culprit.

[pwuser150469741418]

Na bro, not always original. Jo pumps 1 litre petrol pe 50 ML chori kar sakte hain wo oil original nahi rakhenge kabhi. It's my way of thinking. But yea few big pumps do have original oil.

[pwuser150469741418]

Yup, why are you switching away from Shell? I find it very reliable to be honest.

[RehanBhatti]

In my humble opinion all engine oils r good if they r original.

[pwuser150469741418]

Ye bhi munasib hai

Cultus engine is from 1990s tech and this engines requires zddp which is present till sL grade... Shell 10w40 is SN which does not contain required amount of zddp for cultus carby.. Im using havoline 10w40 sj which contains required amount of zddp i never used 20w50 of any engine oil company in my car​you havent read my post i buy havoline from very trusted shop have been using shell from f6 shell pump and now in my next oil change will opt for zic x7000 which is sL grade (havoline is making tappet noise at cold start otherwise it performing good) this zic oil is being used by @hassantahir2 in his cultus carby and khyber this engine oil has more cleaning power than other oil...

I ordered the same oil too. And I am facing crankshaft rattle at cold start with Havoline 10W40 oil​
