Known brand reliabilty for my generator.
I have used this for our petrol generator and have no complaints. It is a known brand, and I need to know I can rely on ity to do the job for a years duty over winter. The price is competitive, and no issues on delivery or packaging.

Ottimo olio per la mia Citroen 2cv, il motore diventa più silenzioso e una piccola perdita d' olio è scomparsa. Sarà d'ora in poi il mio olio per la mia amata " Camilla" .
