Golf 7 TGI (TSI with natural gas ⛽️) - wrong specs engine oil

[gianry]

Hi,
during the last car service it was dropped in a wrong specs oil. Castrol EDGE 5W30 C3 instead Castrol Magnatec 5W40 A3/B4

I've experienced a strange metallic noise with low external temperature ( 5 celsius degrees) at engine start. After one minute engine running the noise has gone away.
Someone told me it was a n issue about hydraulic lifters with poor oil.

is it true ?

If you know its the wrong spec oil take it back to the mechanic who did it & tell them to change it for the correct oil...& yes its likely to the tappets/lifters...
