Is 5w 30 to thin for a 110k 172?

[_Alex_D_]

Costco have some Oil on offer at half price. Packs of 3 litres. 6 litres would cost £22. Specially designed for Voltswagen FSI engines, fully synthetic.

Thing is it's a great price but would it be no good for my engine? I think 30 bit means viscosity at normal running temp. So it would be thinner. A lot of my journeys are 10mins in week and 40mins at weekend.

Any advice appreciated. I know it should be 5w 40 and thats whats in at min. (Millers Fully Synth)

Wouldn't run anything else but 5W40 in an RS, especially one on high mileage.

Might not be good mate.. £22 + new 5w40 is not going to be cheap, although i got 0w30 for free & through it in my old 80k 1.2, jesus was it tappy.. 10 mins later.. oil changed lol.. there is rumor that using that thinner oils can clean the engine & remove carbon deposits that are sealing your pistons, 100+k engine will more than likely have alot of carbon in the head/pistons

The wrong oil, although cheap, isnt necessarily a bargain.

Those carbon deposits that seal the pistons isnt neccessarily a bad thing
