Cam problem in cultus efi

[TahaMehdi]

can I find 10w40 in api SL and earlier, besides sgo. I have heard that sgo quality is pathetic

I have researched a bit, but I am in doubts. A mehran also uses flat tappets and so does my cultus efi, there must be certain improvements in cultus tappets and cam to minimise the wear and tear. Besides, ppl quote of cam failures in classis and muscle cars. And arent the latest grades such as api sm and sn backward compatible??? A neighbour owns a 2008 efi cultus and his car has been driven 118000 kms entirely on petrol. He uses shell hx7 api sm/sn from day one even after the viscosity changed to 5w30. But he has never encountered any problem. His engine still sounds like new. I quoted his case to my mechanic so he said "ous ki qismat achee hogi warna in oils pe yeh model fail hojaata hai"

Well I have also seen many cultus cars being driven on sm and sn rated oils with no problems as well. But your car has got a problem which you got fixed better to stick to sg or sj oils so problems don't arise again. I don't think they might have done improvements in cam design. Yes you are correct mostly classic and muscle cars faced this problem and these oils are backwards compatible, but still these cars also had cam failures even though oil companies say they are backward compatible.

By the way did you check what other members are suggesting you to check.

You can go for zic m 15W-40 in sj grade or zipex 10W-40 sj.

Previously I was also using zic but got a fake product hence shifted to Fuchs from hascol pump. Fuchs has sj and sl products both in 20W-50. As its a company operated pump one on shahra-e-faisal hence no problem of fake products. Secondly I emailed Fuchs Germany because they didn't have hascol on their website but they confirmed hascol are their partners in Pakistan.

zipex has been discontinued. U may use zic 5000 10w40 diesel oil

I saw zipex at some shops, so that is why I was suggesting it. Well it might be the fake one.

Hassaaniqbal92 is correct you can also go for zic 5000 which is 10W-40 sl grade or zic sd 5000 which is 15W-40 sg grade.

Diesel oils in gasoline engines are safe if the api rating says so like zic 5000 is cl-4/sl hence it means primarily it is for diesel engines with cl-4 ratings but can safely be used in cars with gasoline engines and sl grade requirements. Many people are using delo gold ultra in their petrol cars as well.

well I wud stick to 10w40. What would you recommend, zic 5000 or sgo premium api sg???? I'll keep zic m as a backup. And what drain interval should be followed when using diesel oils in gasoline engines???

The cam would fail again very soon if it is not broken in properly, regardless of whether an SC or SN oil is used.

Break in was achieved properly

There are reasons why diesel engine oils are called so. One should better stick to gasoline oils if he has a gasoline engine. U need not to worry about zddp. Although all api grades including sm and sn are backward compatible, the cam failures have only been quoted in classic muscle cars. All the latest api sm and sn oils are perfectly fine to be used in suzuki engines such as mehran, fx, alto, baleno and efi cultus. U just need to choose the correct viscosity

Then y did my cam fail in the first place????

In my opinion stick with sgo sg rated oil and no problems. And for back up zic 5000. Frequent switching is also not advised. Diesel oils also have a drain interval similar to gasoline oils regardless of you using it in diesel or gasoline engines.

Make sure your mechanic has not disconnected the thermostat valve and you are using a proper coolant like caltex, toyota, fuchs, honda.

umm relatively new, not, that engine's design is before 1990. and diesel oils are superior to gasoline oils usually, because they have better detergents(to keep the engine clean) and are more basic(to counter acidic substances produced during combustion. fleet oils(to be used in variety of vehicles, diesel, petrol) are engineered just like diesel oils and are used in vehicles that last(like taxi fleets of a company).

. Heads whose leaks have been repaired leak again as they cannot withstand the optimal temperature of a running car.

Probably u had used fake oils

Agreed.

It wud be a real stress for ur car if u switch from api sn to api sg. Just stick to api sn. No need to degrade ur car

yes i will most probably use shell helix hx5 from now on

[hassaaniqbal92]

yes i will most probably use shell helix hx5 from now on

Whats wrong wid using a premium grade api sg or sj oil??? It would be cheaper too. You are spending more, and that too on something which will harm your car
