I know we've been down this road before. Not allowed to change my own oil cause I'm a condo dwelling geezer. I have a two liter, direct injection HyunKia engine. No real indication of fuel dilution and I'm not planning on getting a lab report. I'm using SuperTech syn on a 6K oci in order to get the odometer to a number divisible by 5K. I have a nearby tire store and a fistful of $10 coupons (really slightly more than $15 when they get all the fees and taxes tacked on).
Currently running 5w30 on the ST syn, and have run 5w20 Maxlife and VWB all without incident.
For 5w30-- it's hot in Missouri, notice no mileage change, it's a d.i. engine, it's probably sheared down to 5w20 anyway.
For 5w20-- that's what it says on the oil cap, less viscosity improvers means more oily goodness, .001% more gas mileage will buy me a c-store hotdog annually and I should take it.
I'm going in next week, using my Valvoline Conventional for $10 coupon (hopefully they won't reject me since VWB is shifting over to semi-syn marketing), and realize this debate has gone on before (and checked out those threads). Wide vs. narrow, thick vs. thin are ongoing debates on here. One more time-- just like a set list for a classic rock band full of 70 year olds.
