Top car mechanic Scotty Kilmer has warned petrol and diesel motorists could “clog up” and break their engines by using a common fix. The leading motoring mechanic stressed that the car sealers used to stop oil leaks could backfire if motorists make a crucial error. He warned motorists to always check dealers before reporting inside their vehicle with any lumpy solution best avoided.

Scotty stressed that a "clumpy" solution could “clog” oil passageways, making it impossible for engines to function properly. Instead, Scotty warned that sealers poured into engines should be clear through in a simple tip may are likely to be unaware of. Speaking on YouTube , Scotty said: “Today I'm going to talk about chemicals you can pour in your engine to help stop oil leaks.



“Sometimes they can work, first change your engine oil, you don't put it in dirty oil. Then you just pour the stuff in. “But some can clog up your engine, here's how you can generally tell.

This, as you can see, is a clear polymer. It looks like water. “If you pour out a bottle of sealer and it’s all clumpy and has pieces in it, don’t use it.

Odds are it’ll clog up your oil system instead of fixing the leaks. “Because you want to fix an oil leak, you don't want to lock up your engine by clogging up the little oil passageways where there’s no oil flowing so the metal runs on metal and your engine breaks. “So remember if you’re going to try an oil seal leak, clear is the way to go.

” Scotty's comments have been corroborated by motoring experts with ProTyre Autocare also warning that additives can come with considerable risks. The car servicing experts admitted the solution can do “more harm than good” later down the line. ProTyre Autocare explained: “Be aware that many oil additives only provide a quick, temporary fix for small leaks.

“One-off emergency use will not necessarily do your engine any harm, but repeated use can do more harm than good. After a while excess additives often settle and clog up the system. Also, leak-stop additives aren’t a magic wand that works everywhere.
