Reveals wear protection differences in multi-lubricant oils
Using advanced tests at the Tribolab of Luleå University of Technology, trainees Theodor Hulthe and Albin Vikström have analyzed the abrasion protection of three popular multi-sprays. The results? Not all multi-sprays are created equal – and this could influence consumer choices.
Multi-sprays are everyday products with a wide range of uses – from lubricating hinges to loosening rusted bolts. Despite the abundance of brands on the market, independent studies comparing their performance have been scarce. Theodor Hulthe and Albin Vikström, two of this autumn’s trainees at Luleå University of Technology, decided to investigate: Are there differences in the abrasion protection provided by various multi-sprays?
In their report, Ball on Disc Analysis of Multi-Sprays, the duo tested three popular products – WD-40, 5-56, and Rivolta T.R.S Plus – by simulating wear in a ball on disc set-up in Tribolab at LTU. The results indicate that one of the tested products provide significantly better wear resistance than the other two products of the study.
"It was fascinating to see how small differences in product design and usage could impact their performance. For instance, shaking the can before use could have a bigger impact than one might expect" says Theodor Hulthe
Beyond comparing the products, the researchers discovered that wear increased when the same test ball was used multiple times, as well as with smaller wear track radii. This suggests that both the condition of the tool and the application conditions of the spray matter.
"We hope our results can not only help consumers make better choices but also inspire further research into these products," adds Albin Vikström.
The study faced some limitations, including differences in testing conditions for certain products, but it opens the door to further exploration. A particularly intriguing avenue for future research is how much shaking the can before use influences the results – something that is often recommended but rarely scientifically tested.
Tekniksprånget
Tekniksprånget is an internship program where young people who have completed a science or technology program at upper secondary school can try out the engineering profession through a four-month paid internship. Since its inception in 2012, almost 7,000 participants have gained an insight into the profession with over 220 employers in more than 100 locations in Sweden. The aim is to inspire more people to choose technical education and help employers find the engineers of the future.
