Redline 5W-30 no longer meets ACEA A3?

[quadrun1]

I was at a local auto parts shop and noticed on the new bottles (blue label) that the Redline 5w30 is no longer A3 rated, but rather, A5. Same with the 10w30. HT/HS visc too low?

They had a couple of bottles of the old stuff (red label) and it stated "A3-96".

Looks like if I try this stuff, it'll be the 5W-40...

The red 10w40 label doesn't say A3.

Yikes!! Is it crappy oil too?

Redline uses a different method to derive HT/HS and it's quite possible it never met A3 under the method Mobil/Amsoil used. Although highly unlikely due to RL's thicker viscosity.

ACEA specifies method CEC L-36-A97 (Ravenfield) be used for HTHS measurements. ASTM methods D4741(Redline) and D4683 (Amsoil) are essentially the same as CEC L-36-A97, although the tapered plug machine (D4741) is technically identical while the tapered bearing machine (D4643) isn’t.

Both ASTM methods require the use of CEC reference oils to calibrate the machine. They will give the same results.

The shear values I shared here the other day from testing on 12/2000 are a combination of D445and D5275 so we can compare apples to oil

, (little analysis humor).... apples.

I posted both RL and Amsoil ( ATM) for comparison. 2 old M1 formulas too.

While a bit dated gives you and idea of ONE aspect of the formulations. This is more real world IMO for shear resistance.

Note that RL,and the last 2 M1 formulations before Super Syn showed essentially 0 shear. Less than 7 % for Amsoil is excellent too. As a matter of fact in a engine that I want to derive some extra HP from, the separation characteristics of that fluid may need to shear a bit to reduce friction if well formulated in other aspects.

HU! You sound a lot like you know your s...! So RL, Amsoil,and M1 are all superior oil.

Yeah, Terry knows his stuff alright! When he talks you listen!!!!

Don't say that too loud your bike might hear! Actually for those that care I have some 10w40 with the new bottle labels and it still has A3. Not that I'm too worried about it.

Redline is now $5.76qt at Advance Auto Parts. It also only meets A5/B5 specs according to the back of the bottle. FYI.

A month ago it was $7.99 at the local Avanced Auto. Did they lower the price at your local AA?

buster,

Do you know if that is a permanent price on the Redline through Advance?

I can't seem to find any for pricing on their website.

The advance autoparts around me (ne ohio) has it for 5.95/qt also they give me the 20% preferred discount on it....

I asked at my Advance Auto. They said clearance. When the shelves are cleared they will no longer stock it.

The methods are essentially the same. MolaKule found out. See this thread.
