VLS: UK workshops still unclear on oil specs

Around three in ten UK workshops are still unclear about the meaning of oil specifications, according to the Verification of Lubricant Specifications (VLS), the independent body that investigates and resolves lubricant product complaints.

VLS, with the support of oil specialist Comma, surveyed the attitudes of UK workshops to engine oil via a web survey of over 12,000 UK workshop contacts.

The results, it says, suggest that many technicians still do not fully understand what oil specifications and marketing claims mean, and are selecting oils based on price, not suitability. It warns that language around lubricants can be complex and confusing.

VLS asked technicians, “In your own words, what do you think is the difference between ‘OE approved’ oils and oils that ‘meet the requirements/specifications of a manufacturer’?”

Most respondents understood these terms, says VLS, identifying that “OE is the right oil according to the dealer. ‘Meet the specification/suitable for use’ means it meets the requirement but isn’t the original oil” and “One is generic and one is specifically designed for those engines”.

However, around 30 per cent either didn’t understand the difference, didn’t think there was a difference, or adopted the view that there was no difference, ”just price”.

When asked to rank oil specification descriptors in order of which they thought was ‘best’ and ‘worst’, the majority identified oils that were said to be OE-approved as superior, seeing little difference between the other claims (‘meets the requirements of’, ‘suitable for use’, ‘recommended for’).

Opinion amongst workshops was split when it came to whether engine oils that ‘meet the specification of’ are just as good as OE-approved oils.

Whilst 51 per cent agreed, many were unconvinced, and 27 per cent disagreed.  Lubricant manufacturers invest significant sums in gaining OE approvals for their oils, says VLS, yet many technicians seem unconvinced.

According to the survey, most workshops said they used online oil selectors or Autodata to find the correct oil. Quality and suitability were the key factors driving their product choice. However, several workshops did rank price as the most important consideration. According to VLS chairman Harald Oosting, that is a cause for concern.

“We know that workshops are under pressure, trying to save money wherever possible,” he said.

“However, using cheaper, poorer quality oils or ones that do not meet the correct specification risks the protection needed for owners’ vehicles.

“Poor quality or the wrong oil can cause damage to emission control systems, accelerated wear in gears and bearings, and the formation of piston deposits, leading to increased maintenance costs and, if left unchecked, eventual engine failure.

“Modern vehicle engines require sophisticated lubricants using advanced chemistry. Even the slightest change in the formulation has the potential to reduce performance over the short term and cause engine damage over the long term.

“Compared to standard formulations, cheaper products might contain reduced quality base oils, fewer additives or even untested additives. This can significantly affect the lubricant, resulting in poor or possibly even dangerous performance compared to genuine products.”

Most workshops (over 80 per cent) source their engine oils from motor factors, says VLS. Whilst some workshops were stocking 60L drums and barrels, 37 per cent kept 10 or more 5L packs on site at any one time, highlighting the complexity of product requirements and the dominance of the smaller pack size to cater to different engine requirements.

The survey also asked respondents about industry bodies they had heard of. As expected, the data showed a high degree of awareness of Trading Standards, with whom VLS has a Primary Authority relationship; and ACEA, the European Association, which sets engine oil specifications.

“Twelve years ago, VLS did not even exist,” said the body.

“Now, over 33 per cent of survey respondents have heard of VLS, representing a significant shift.

“Work continues through events like Automechanika and key industry publications to reach the rest of the workshop audience so that all technicians become aware of VLS’s role in protecting and upholding standards in the lubricants industry.”
