Ultimate protection and durability for metal to metal contact. The base oil is still produced for Phil by the same independent California refinery since 1971 and the final blending is performed by an in house chemist at the Phils factory.
I started using Phil Wood in 1975. I just bought the tenacious oil and I would agree that it does a much better job at lubricating the chain than the dry type of lubes especially if you are riding long distances and in varying weather conditions. Yes the chain may get a little road grime, but a cotton cloth after a long ride does the trick. I clean the chain,chain rings and cassette about once every 3 months and re-lube and I have not had a problem especially living here in Florida.
This is one of the best chain oils and general purpose oils available. It is thicker, and will get dirty and black, but it lasts and lubricates. It will totally silence your chain. For cleanliness, just wipe the dirty chain down with a solvent-wetted rag; apply one drop of tenacious oil per link, then wipe off the excess with a dry rag. It will not stay as clean as the modern dry lubes, but it will lubricate SO MUCH BETTER. I just couldnt stand the dry lubes that wont even last 100 miles (I have tried them all.) If they figure a way to make it stay clean, I will give it 5 stars.
Phil Wood Tenacious Oil is by far the best chain lube available. It is a high viscosity oil which will produce a quiet chain and is far better than the thinner lubricants which almost act as cutting oils when mixed with road dirt.
Ive experimented with a variety of lubes for the chain and Im convinced that Phil Wood Tenacious oil is the best. Smooth quiet shifting. I apply it while the chain is off the bike one drop per link. Wipe off the excess .
Great stuff works very well it is also a very good chain lube as well, just go light on it. One drop per link and wipe off the excess sticks very well and lasts forever. I have used pro link pro gold in the past and I prefer the Phil Wood oil over any other lubricant I have used and it is cheaper than most.
