07SGT Posted October 22, 2012 Report Share Posted October 22, 2012 would 0W-20 synthetic be preferable to 5W-20 in the Shelby GT 4.6 3V? Both provide 20 weight protection when hot and the 0W is going to flow quicker at start-up to reduce wear. Thoughts? Link to comment Share on other sites More sharing options...
shelbyeuropa Posted October 23, 2012 Report Share Posted October 23, 2012 That's funny back in the old days we use to run Castor-oil 10-40W during the summer and 20-50W in the winter. Now I guess it depend where you are located I'm in Mid CA where there is no snow and about 28deg is the lowest but over 110+ in the summer so I run 0-30W or 5-30W synthetic is what I run. If you are located in an area that is 0- deg then I can see the 0-20W. Link to comment Share on other sites More sharing options...
