Attention: TDR Forum Junkies OK, kids. There's been a number of folks asking what mileage gain, if any, has been noticed using this stuff since it was made available (or discovered it was available) last year. I've been using it constantly since then. So I decided to go "cold turkey" and kick the habit for a few tankfuls and see what happens.
I have below 9 fill-ups listed starting in mid May. My truck is my daily drive and usually runs around empty (what a waste, huh). Save for 2 fill-ups (noted) they were all done around the valley with a mix of town and short freeway or out-of-town, 2-lane, country trips (60-65 mph over a 7% grade hill about 4 miles up/down both sides).
The 2 out-of-town fill-ups were to the BullyDog event in Pocatello a few weekends ago. Those were both late afternoon drives in roughtly 90 degree temps at about 82 to 85 MPH on the freeway across southern Idaho.
By the way, I'm running 285/70 Toyo Open Country tires, which give me about an 8% correction factor. Mileage is given both as determined via the odometer and corrected for the tires. The speed indicated above on the road trip is corrected for the tires (i. e. actual).
All fuel was purchased at Flying J stations, including when in Pocatello. The quantity of Amalgamated used is according to their recommendation (1 oz. per 3 gallons), or just a tad more
1: Amalgamated used.
411. 6 miles
29. 054 gallons.
14. 17 mpg
(15. 3 mpg, corrected)
2: Amalgamated used.
421. 4 miles
28. 690 gallons
14. 69 mpg
(15. 86 mpg, corr. )
3: Amalgamated used.
416. 7 miles
28. 251 gallons
14. 75 mpg
(15. 93 mpg, corr. )
4: NO Amalgamated
408. 3 miles
27. 770 gallons
14. 70 mpg
(15. 88 mpg, corr. )
5: NO Amalgamated
277. 1 miles
18. 546 gallons
14. 94 mpg
(16. 14 mpg, corr. )
6: Amalgamated used
288. 1 miles
18. 873 gallons
15. 26 mpg
(16. 49 mpg, corr. )
7: Road trip to Pocatello, Amalgamated used
302. 6 miles (at about 85 mph, w/tail wind)
20. 255 gallons
14. 93 mpg
(16. 13 miles, corr. )
8: Back from Pocatello, Amalgamated used
353. 4 miles (at about 82 mph, w/head wind)
24. 816 gallons
14. 24 mpg
(15. 38 mpg, corr. )
9: Amalgamated used
468. 8 miles
31. 506 gallons
14. 88 mpg
(16. 07 mpg, corr. )
So, the bottom line: either Flying J has pretty decent fuel already and the Amalgamated can't improve it as far as mileage goes, or it just doesn't make a difference.
However, I do beleive the engine sounds and feels smoother on Amalgamated. And it seemed to start easier when cold.
FWIW:
