Engine oil VALVOLINE or OEM Honda

Valvoline SynPower Full Synthetic 5W-40, VW502 approved. I use it in our '07 A4 (over 100K miles) and plan to use it in our '16 GSW.

5W-30 Valvoline SynPower (full synthetic) and Mahle filter since I picked this car up at 89k in '11. Just cleared 175k last week.

I think what helped as much is the valvoline oil. Valvoline really agrees with my motor. Not sure why I have trouble with some of the other blends, but it's really quiet with the ashland add-pack.

Valvoline VR1 non synthetic. It is one of the ZDDP oils. Reasonably priced and the Z seems to like it.

[Valvoline SynPower](http://www.valvoline.com/products/brands/synpower/full-synthetic-motor-oil/5) is what I have run since I purchased my 2012 Subaru Legacy.

Anyway, when I had my Passat 1.8T and sludge issues were the big fad, my oil of choice was Valvoline Synpower 5w40. It met 502 and was not a synthetic blend but rather a real synthetic.

I use valvoline because it's common and it does the job. My auto mechanics instructor also recommended it because he said most of the engines he'd taken apart that had run valvoline looked pretty crud free.

The Fit is an awesome car. I have an 09 that has ~66k miles and NOTHING has gone wrong. Just the scheduled maint., oil changes (10-12k miles), and thats it.

Strictly anecdotal, but at 56,000 I switched from the usual suspect Castrol to Valvoline Synpower. Engine starts more smoothly and observed mileage on highway has gone from approx 30 to approx 34 mpg.

I use 20/50 Valvoline year round....
