Add a turbo and use it at all aggressively or turn it off on a 90 deg day without raising the idle to 1,200 to 1,500 for 30 seconds to 2 mins, before shutting it down, then a full synthetic higher end oil is worth it. QUOTE]
By this I mean boutique oils like Amsoil Signature Series or Redline that are group 4 PAO and group 5 POE/Ester oils. Also add in Mobil1 Extended 5w-30 in has some group 4 and can handle some more heat and can be purchased at Walmat for $28.00 for 5Qt jug. That's what I am running now and I will be dumping at 1,000 miles. That same Mobil 1 Extended oil I use at work in our Ford Transit Connect that I do oil changes at 15,000 to 16,000 miles with a Fram Ultra and oil analysis comes out go for the oil. It is not a DI engine (direct injected engine) so we can get those miles on that oil, If it was a DI motor we would start out at dumping it at 10,000 miles and look at the fuel in the numbers and wear numbers to see if we could push the oil to the 15,000 number we safely get with a non-DI engine.
ALL the other oils sold at Walmart are group 3 oils with the exception of Pennzoil Platinum comes in at a group 3+ since they make it out of natural gas. That oil I would guess is a 10,000-12,000 mile max oil with an oil analysis to make sure.
