1. DINOIL PARTNERSHIP: FROM LAMBORGHINI TO NASCAR WHELEN

Before even talking about technical data sheets, it is worth looking at something that is immediately visible on the label of Dinoil Professional bottles: the presence of the Lamborghini and NASCAR Whelen Euro Series logos as technical sponsors .

This means that Dinoil oils have been chosen as a technical partner in contexts with extremely high mechanical stress : high-revving engines, high temperatures, heavy use, and zero margin for error. In other words:

• if an oil survives on the track, with the temperatures and revs of a racing car, in real life on a 1.6 turbodiesel or a 1.2 petrol it will have a decidedly easier life;
• the same formulation philosophy is carried over to products for road use, with viscosities and specifications calibrated to the manufacturers' needs.

It's a clear message: Dinoil was not created as a "supermarket" oil , but as a lubricant that must be able to stand up to even when the engine is really mistreated.

2. WHO IS DINOIL AND HOW IS THE RANGE STRUCTURED?

Dinoil Professional is the unique line with which the brand presents itself on the market: no separate “basic” or “premium” ranges, but a single professional quality standard , divided into:

• different viscosity grades (0W-30, 5W-30, 5W-40, 10W-40, 10W-60, etc.);
• different specifications and approvals per manufacturer (e.g. PSA, VW, MB, BMW, etc.);
• products dedicated to cars, motorcycles, commercial vehicles, marine and industrial applications.

A concrete example is the bottle you showed in the photo: Dinoil Professional 0W-30 “Formulated for Peugeot Citroen” , with the PSA B71 2302 & 2312 specifications indicated on the label, usable on diesel, petrol and hybrid engines of the group.

This “one quality, multiple applications” approach is interesting because it makes life easier for:

• workshops , which do not have to manage an “economic” and a “premium” line, risking confusing them;
• end customers , who do not find themselves with oils with similar names but different qualities.

3. WHAT MOTORISTS THINK

End user reviews converge on some recurring aspects.

✅ What is appreciated

• Smooth, quiet motor : Many report smooth operation, with reduced noise especially when hot.
• Normal oil consumption : if the engine is healthy and the intervals are correct, no abnormal increases in consumption will be recorded.
• Quick cold starts : with viscosities such as 0W-30 or 5W-30 the lubricating film arrives quickly even in the coldest climates.
• Price-perfect : It's not the cheapest on the shelf, but it costs less than several "name" competitors with the same specifications.

⚠️ The most frequent doubts

• Little-known brand : many drivers have never heard of it before the garage's recommendation.
• Lack of major advertising : Not seeing commercials or banners, some people struggle to trust you at first sight.
• Very technical label : for those not in the know, acronyms like "PSA B71 2302 & 2312" don't mean much; a mechanic's translation is needed.

In general, those who trust their mechanic and try Dinoil for more than one service tend to consider it a reliable oil for daily use , especially on cars that are a few years old.

4. FEEDBACK FROM THE WORKSHOPS

For a brand like Dinoil, the opinion that really counts is that of the independent workshops , who use it every day on different vehicles: from private city cars to company vans.

🟩 Advantages for the mechanic

• A single quality standard : no “good oil” and “cheap oil” under the same brand, but a single professional line with different applications.
• Simplicity of warehouse : with a few well-covered references (0W-30 PSA, 5W-30 C3, 5W-40, 10W-40, 10W-60, etc.) the workshop manages a large part of the circulating fleet.
• Reliability over time : those who have been using it for years do not report problems related to inadequate lubrication or abnormal sludge formation, if the services are regular.
• Balanced commercial margin : allows you to offer the coupon at a fair price, without sacrificing product quality.

🟥 The precautions to take

• Explain the choice to the customer : the customer who reads “Dinoil” for the first time needs to understand why the workshop uses it.
• Respect the manufacturer's specifications : the range is unique in terms of quality, but the specifications vary; it is essential to use the correct Dinoil (e.g. 0W-30 PSA on Peugeot/Citroën that require it, 5W-30 VW for the VAG group, etc.).
• Don't improvise on intervals : as with any oil, if you double the mileage between one change and the next, no brand can work miracles.

Many workshops that have stocked it have kept it over time, a sign that the relationship between technical performance and customer satisfaction is good.

5. THE OPINION OF THE LUBRICANT SECTOR EXPERTS

From a technical point of view, Dinoil is rated positively for several reasons:

• Focus on lubricants : It is not a “do-it-all” brand, but a manufacturer that works almost exclusively on oils and additives.
• Formulations aligned with European specifications : products that meet ACEA, API and the requests of individual manufacturers.
• Advanced applications in motorsport : the partnership with Lamborghini and NASCAR Whelen is a real training ground for testing thermal stability, shear resistance and lubricating film strength.
• Protection on high-load engines : some oils in the line (for example the 10W-60) are clearly designed for engines that work under heavy stress.

Those who analyse the product with a technical eye do not consider it a “cheap stopgap oil”, but a lubricant with professional standards and a competitive price .
