Re: engine oil question The spec is 5w-50w (which is hard to find)...I run Schaffer Oil full synthetic 5-50 with an Amsoil filter...
Re: engine oil question Thanks Lifter583. I found some Catrol Syntech 5w-50 and a K&N filter from Autozone. Thanks for the help.
Re: engine oil question Got another oil question; thought this was the best place for it... I have 4,836 miles on the original oil, but it says "OIL CHANGE REQUIRED" Scheduled oil change isn's supposed to happen until 7,500 miles. (2011 Shelby Cobra GT500) What gives? (BTW, no previous indication of oil usage at 50% or 75% in the dash either) Also, I'm going to contact the dealer/maintenance department and ask the same question. I'll get back to you all if I find an answer...
Re: engine oil question Well, I got the answer... The "Oil Changed Required" comes on every 6 months or 7,500 miles whichever comes first. So If you don't do all 7,500 miles in 6 months you will get the same warning. Simply reset the oil usage warning. Listed in the Mustang owners manual - not the shelby guide. Hope this helps.
