These arrived today, picked up all 3 for £35
Took them over to my local indy - TWG Automotive. Will had a quick look, I think he said he's not used Archoil before but the concotion seemed to be solvent free which was definitely a positive. So will be a first for us both.
Poured the recommended amount (roughly) of the AR2300 into the engine block. About 50ml left over, shame they dont give bottles with markings on:
It says on the Archoil website for the AR2300 to be fully effective in fully synthetic oils you need to run it for 4000 miles. I don't think I'll do more than 1500 before my service is booked in but took a snapshot anyway, so will describe what the effects are after the service. Some cleaning is better than none in my opinion.
Will keep you all updated!
