Recommended for tractors like my Prius.
This was recommended to me for my Prius from 12 BC. My Prius thinks he is a Hummer in winter. Definitely recommend!

High quality and good price
The classic oil. I use this on my V6 Audi. As the engine has done a few miles now, thinner oil is pointless and I find the slightly thicker 10W-40 oil reduces oil consumption. I have tried various oils including Shell, Repsol and Comma, all respected and high quality products but I have found this Castrol GTX to be the best all round but for a classic sportscar. The A3/B4 designation shows that it conforms to Audi-VW requirements.
