Pentosin Dot 4LV in a G37x?

[GZRider]

The left rear caliper has stuck on a few occasions after bad weather trips and both rears have pretty significant corrosion (base sliding cast iron calipers) so I ordered a pair of Raybestos R-line replacements, new Akebono ASP pads and 2L of the Pentosin Dot4 LV fluid based on the thinking the car might see -20f this winter but now I am a bit concerned I made a mistake going with a LV fluid for this application. Any insights would be appreciated.

DOT 4LV will work just fine. I have it in most of the cars I maintain. It's a must on newer cars calling for DOT 4LV, but since it's less viscous than regular DOT 3/4 it can translate to more transparent ABS operation.

I've noticed a change in the brake pedal for the better in one case.

Pentosin says it's fully backwards-compatible with regular DOT4 and DOT3 and can even be mixed. I have some myself that I planned to use to exchange the fluid in my wife's Fusion (which specs DOT4 LV) and was going to use it in my G35X as well.

Thanks guys! I have a bad habit of overthinking this stuff.

Just to reassure you (more):

NOTE: Low viscosity brake fluid can be used in vehicles that do not require a low viscosity fluid; however, standard DOT 3 or 4 brake fluid should not be used for top off in vehicles that require a low viscosity brake fluid. This action will reduce the low temperature properties and decrease the safety performance of the fluid.

You did not make a mistake using LV

New parts installed and the LV fluid works great in the G at warm temps, improved pedal modulation and feel over 1 year old Valvoline 3/4. Thanks again to all that replied.

I use that in my Passat. Sure it is expensive but it is the same stuff the VW dealer sells relabeled. I am not sure if I could use non LV fluid but I am happy with my brakes the way they are anyhow and would not switch from using that. Unless you have a strange car that takes some weird special fluid you can use the LV. Some people might say using that is overkill but I have a feeling they are the ones who have a beat up old clunker that barely runs!!
