Wow, what a game changer. Just did front gear oil on both F150s and these new Valvoline soft oil bottles are amazing. At least on the 2011. Snip the tip and squeeze it in (uhh…), front dif was filled in about 2 minutes! Now the 2018 was a different story, that engine oil pan is really tucked up against the pumpkin! Had a hard time even getting to the fill plug and ended up using my suction gun to inject the new oil. Not nearly as easy as the other truck but I figure both should be a breeze on the rest end!
