This came out as the first oil to use a new synthetic technology called GTL (gas to liquid) produced at the Pearl plant in Qatar, and marketed as PurePlus.

Nowadays quite a few other quality oils all over the globe make use of this base stock. This Shell oil has recently been reformulated in some markets (including Australia) and in my opinion it has lowered the amount of GTL being added. This is backed up with the fact that the oil has been dramatically lowered in price during specials something that I never noticed before.

I will continue to use it and monitor its performance into the future but am considering a switch to a different 5w-40 oil.

Shell is a massive oil company and I trust them to make a great product especially if they put their name on it. Other companies buy oil and market it. I have been using Shell, full and semi synthetic oil for years now. Four and two stroke. All great. I buy top shelf for my good vehicles and cheaper oil for my old bombs.

Engine runs smooth and quiet with the HX7 10W40. Good fuel economy also. I use it in all my vehicles being a 2007 Falcon, 2015 Elantra and a 2012 lancer. Trusted brand that i have used for decades. Recommended by top manufacturers. Use with confidence. Keeps my engines clean and protected.

I bought several containers of this oil 10w40 grade, when it was on sale at Repco and Super cheap auto for 20 dollars for 5 lites a while back. I have used it in a few different vehicles and I haven't had any issues. The oil has the SAE specifications of sn/cf which is good as it meets the current requirements. It is one of the three brands I trust. I only use Shell, Castrol or Valvoline nothing else. The brand of oil is a reptuable one and are well known so most car manufacturers are OK with using it. Overall I am happy with this product.

Started using this engine oil at my last service and the engine feels much smoother. It has a cleansing technology, or at least that's what it says on the box!, which might be great at cleaning the engine deposits! I highly recommend it to anyone using old cars like mine!

Swapped to shell helix around a year ago and found immediately that the car ran smoother and was a heap quieter on startup. Shell reckon that there is around a 3% fuel economy gain so that offsets the small extra you pay. I was told shell supplies Hyundai ex factory, so it's good to stick with the factory oil even though I service myself

Used this oil on my previous 88 integra. It does its job, however did not feel any extra throttle response, or better mileage.
But one thing for sure is the cleaning ability.
The components when looked through the oil filler cap used to have a light yellowish/brownish tint to it. After just one oil change of the 5W-40, ran 5000km and its all back to shiny silver!

No other brands have cleaning agent package as good as the Helix Ultra.

My dealer uses Shell Helix Ultra Extra 5W-30 fully synthetic oil in my X-Trail TL Diesel. The M9R engine in the X-Trail is very fussy with oil requirements in that it must be fully synthetic and it must meet ACEA-C3 standards to be suitable for the Diesel Particulate Filter.
Shell Helix is an excellent oil - it maintains a clean engine and it seems to suit the DPF-fitted diesel very well. Highly recommended.
Not the most expensive, high quality, good cold starting in Winter
Nothing, really.
