The savings are worth it in this package.
There is an immediate notice when products are used (quieter, smoother, more responsive).
I thought my 2003 truck was running as close to perfect as it could get at 130k miles; I could feel the friction modifier going through the engine; my wife rode along on the highway last week and noticed the power and silence, idle has smoothed to a near electric car mode at stoplights. The fuel treatment went in a few tanks after a can of BG44 and the supercharger is even more aggressive for passing on the highway while climbing mountain passes under load (Montana to Utah) is much less of a concern. Archoil passed my testing, and I'll soon be adding it to my 54 year old classic unrestored original owner convertible Mustang 289 (442)- this with her redline motor oil should keep her in fighting form.
Used the fuel treatment and can honestly say i felt a difference on the first fill up. have not used the friction modifier yet. Shipping was fast arrived sooner than scheduled. So far pretty great.
I have been running arch oil for the past three years, in three different 7.3 power stroke engines. Every third oil change, I send Blackstone Labs a oil sample. On my F250, This last oil change states, “ engine is getting stronger “ no visible signs of wear! I truly swear by this product.
Ordering made easy and delivery was ahead of schedule great job
