Any Automobile Engineer or Hyundai Car User here ?
Any Hyundai diesel car user here ? specifically Hyundai fludic Verna CRdi 1.6 SX ?
have a long argument with one of the garage owner regarding the Engine Oil for my car.
As per him below Shell engine oil is not at all suitable for Verna diesel, It is for trucks and heavy vehicle only .
He deals in hyundai spare parts , engine oils etc, He insisted to buy suitable engine oil from him , he is quoting price around 1550 rs for 5L. he told me first time he saw this kind shell engine oil. It is not good. to support his argument,he also called someone(told me hyundai engineer) . that engineer also trying hard to make me change my decesion and buy oil from them . he is like" sir it will cease you engine immediatly" “it is not for Hyundai verna diesel” .
Actaully I bought the oil from Amazon, had got some discount, I bought after proper reaseach . I read the review on the product page where people say it is a manufacture recommended oil for fluidic verna diesel 1.6 sx.
Also checked hyundai website , it is mentioned same specification recommended for fludic verna. it is a mineral oil not synthetic/semi-synthetic .

here is the link to the product : https://www.amazon.in/Shell-Rimula-15W-40-Premi...
I am not expert in this field , went with the reviews and article on team-bhp website.

So, he is actually unaware of it. His knowledge is partially right. He is talking about petrol cars.
But do one thing. Ask your Hyundai service center/customer care once. But honestly in the end xxWxx will matter. If you are recommended to use 15e40, then use 15w40, mere truck picture won’t change the characteristics of the engine oil
Along with the picture he also saw another thing and he told me it’s written “heavy duty” means its for Tata Ac, mini trucks , other cars but not for verna fludic diesel. uhhhh.. 
even he shared the image on WhatsApp with that hyundai service center engineer . that engineer too warned me multiple times to not to use this oil for fluidic verna .
He had some yellow color shell helix engine oil , where at the bottom , hyundai is written. so he is adamant that this particular oil is for hyundai.
@bumblefoot @mrKool_JJ @AyushiiiVijay @Simbha3 @mj911 @getready guys. Share your thoughts if possible
You can use, but I’d advise against it. Its for trucks, so it has heavy detergents for cleaning carbon. Better to return it, and buy one for car which is shell helix or any other engine oil meant for car.
I’ve used a diesel engine oil in my petrol scooter of the nearest viscosity which caused performance issues. Will never experiment with my car.
His car is a diesel car.
Nothing will happened .use it (Mechanical engg maintain 300+ vehicles in month)
Experience of maintaining luxury cars(pajero ,mercedes,land cruiser and GMC)
1550 for 5 ltrs = ₹310 /ltr maruti guys sell for ₹550/ltr so proves its reasonable. I doubt any wrong doings.
Diesel car is different from diesel truck.
Cars run at high rpm low torque.
Trucks run at low rpm high torque.
So oil of both is different even though the ratings might be same.
Hyundai logo on bottle asks high premium. But it’s not just that. Even hHyundai must have tested the oil and fine tuned it on its test mules for thousands of kms.
So it’s not the logo but testing and compatibility you pay extra for.
Diesel engines run at low rpm and high torque and petrol engines run in linear scale of power delivery, e.g. high rpm, and high/low torque depending upon engine tuning and manufacturing.
Since, diesel engines run at low rpm, suitable gearing make it suitable it to be used on cars. 🙂🙂🙂 SAE ratings are stringently maintained especially by big manufacturers, Zittoo bhai is in safe hands.
Hey so how was your experience with that oil ?
Wow you own Verna 
It’s totally fine. U can better use Rimula R4. Can u tell manufacturing year?

In the end xxWxx ll matter. 🙂🙂🙂
15W40 means viscosity of oil ll be 15 at cold temperature and 40 means viscosity of oil ll be 40 at hot temperature.
