The oil is excellent. A very light colour and at 11.23ea on sale was a bonus.

I like that it comes in a 1 gal quantity because I had a full system to flush and bleed. Also, I have noticed some reviewers complain that they were cheated because the label says “DOT 3+4” and they think this means that the product is a mixture of DOT 3 and DOT 4. This is mistaken. The difference between DOT3 and DOT4 is the 4 has a slightly higher boiling point which will help resist heat fade. However, the DOT 4 often comes labeled as 3+4 because the two are cross compatible, meaning that if you have a brake system that takes DOT3, it’s OK to put DOT4 into it, and it’s OK to add DOT 4 to the system as a top off. Now when it comes to DOT 5, that is a silicone fluid that is not cross compatible and should never be added to a DOT 3 or DOT 4 system. So the DOT 3+4 product is actually the DOT4 spec, it is not a blend. If you want the full DOT4 boiling point then you must totally flush your system with all DOT 4, and if you add DOT4 to a quantity of DOT3 fluid you won’t get the full boiling point but the compatibility is OK.

This works well and is cheap for full synthetic. I use it when I need to flush a full system.

“Johnsen’s 5034 Premium Synthetic DOT-4 Brake Fluid – 1 Gallon” works great for me. With six adult kids, this Busy Texas Dad is always working on vehicles and checking/replacing/replenishing fluids.After recently bleeding the brakes on my 2008 Lexus ES350, it is stopping better that it did before.
