Baz 0 Posted April 11, 2012 Report Share Posted April 11, 2012 Hi,Has Anyone used 15W-50 oil in their engine here ? I only ask as mine needs an oil change and I've got 5 litres of Silkolene Pro R 15W-50 that I was going to use on my Skyline & wondered if it would be any good ?Baz Link to post Share on other sites
Lukey. 381 Posted April 11, 2012 Report Share Posted April 11, 2012 wouldnt the thicker oil be pumped at a slower rate therefore increasing engine temps? It might be fine in summer when ambient temps are hotter but dont know about winter when its minus* 5w30 is way too thin and 15w50 is only the same jump up in viscosity just my initial thoughts about what bad could happen?

Daverse 175 Posted April 11, 2012 Report Share Posted April 11, 2012 i might be tempted to put some in if it was just topping it up a bit, but I wouldn't use it to fill from empty Link to post Share on other sites
HAMMER_VR6 0 Posted April 11, 2012 Report Share Posted April 11, 2012 I wouldn't risk it. you can buy the genuine vw oil for less than £20. not worth the risk. Link to post Share on other sites
