Penetrating Oil Apr 2019 Test: Which Brand Wins?

done a very good job of coating the nut and bolt, some FreeAll made it all the way down to the washer

made it all the way down to the washer, very low viscosity

appeared to have the highest viscosity of all products tested, thoroughly coated the entire nut and bolt

clearly coated the four bolts, looked like it did a pretty good job

bolt and nut looked thoroughly coated with water, some water remaining on the washer

done a very good job, although not quite as good as Gibbs

started to climb the bolt within about 5 minutes

doesn't look to be quite as good as FreeAll, but still doing a pretty good job of climbing a vertical surface

actually done a pretty good job of climbing this bolt, all the way up to the Plexiglas

has not done a very good job at all

gone up about an inch and a quarter up the rusty steel pin

moved about an inch and a quarter up the rusty steel pin

did not do quite as good as FreeAll, about an inch and an eighth up the rusty steel pin

gone up nearly 2 in up the rusty steel pin, the most distance climbed of anything tested including the real penetrating oils

may have gone up about a quarter of an inch, did not reach the Plexiglas

went up the threads about an eighth of an inch

climbed all the way up the bolt and began penetrating the rusty threads, exact depth not quantified in the transcript

climbed up at least a quarter inch, close to a third of an inch up the threads, called a very respectable job

made it into the threads by about a quarter of an inch

did not reach the edge of the Plexiglas so no thread penetration was measured

seems to have done a slightly better job than 3-in-One Oil at penetrating the rust

not quite as good as Gibbs, but did a pretty good job making penetration at both ends of the nut

obviously did a better job than diesel; some 3-in-One penetrated at the base of the nut and at the edge where the threads meet the nut

left an oily film all over the nuts and bolts but no visible sign it penetrated the rust

does not appear that water did any sort of penetration

second place

third place

not named in the top 3 (Gibbs, FreeAll, Mouse Milk), implying fourth among the real penetrating oils

not ranked among the winning products despite climbing the farthest; the video notes that climbing ability alone does not make a good penetrating oil

worst performer; video explicitly recommends a penetrating oil over water
