joshbl Site Supporter May 20, 2011 #1 I normally use 15W40 magnitec but as castrol have ceased production on that, I bought castrol GTX 15w40. Does anyone know the difference? or is it just a lower grade??

Guy Has gone over to the oily side... Club Member May 21, 2011 #4 15W40's awfully thick. What's your engine and mileage ?
OP OP joshbl Site Supporter May 22, 2011 #5 L reg 1.3 on 79K. I had 10w40 before which I thought was a bit thin so I went for the 15w40 which haynes recommended this time
