Why would I not use the best oil I believe I can get. If nothing else, it's makes me feel like I'm doing the best for my engine.
I realize a Dino might do just as good, but for me, I only use Syn in all mine and my kids vehicles.
Because in the end it does not matter!
Only $60 a year equals $600 in ten years. If you go 18mpg with that truck, that is 3600 miles worth of gas if gas stays $3 a gallon.
(I crack myself up, gas staying @ $3 a gallon..)
I've made 200k+ on many engines and over 300k+ on one with *yesterdays* conventional oils.
Todays oils are much better. ANY 5w-20 is going to be Semi-Syn.
The oil companies THANK YOU! Its your mindset that they love.
Really, unless you can take advantage of major sales to get the cost lower OR EXTEND the OCI (which I would not while you are under warranty which we discussed above) I would look at ANY 5w-20 based on cost.
Lets put it this way, IF you had a accident the insurance company will not pay you any more for the car if you used Syn. Or put new tires on it. They go by the book. Same with a sale.
(call your insurance agent or go run your car at KBB.com, Edmunds.com or NADA.com. You will notice there is no where to input what type of oil used when getting a quote on how much your car/truck is worth.)
But again, money spent is your business.
I've done UOAs with both Syn and Conventional and in normal OCIs in a I4, V6 and V8 the tests came back with the conventional being just as good if not better than the syn. Syn really is only needed for engines that NEED it or extended OCIs.
Just something to think about.
Take care, bill
