Penrite Oil

[Martin]

My Octavia used to swallow at least 1.5 litre of oil per month
Since adding 250ml of Liqui Molly Visco Sabil Plus it has not used any oil, done 5,000km so far
It leaves the cold viscosity the same but significantly increases the hot viscosity

1L per 100 kilometres is a mechanical issue. You could put 10w60 and it still wouldn't make a difference.

Have you checked the PCV and had a wet/dry compression test done?

Sorry I meant 1000 ks not 100ks.
