5w40 amsoil esp

I can get a couple of cases at 6.75 a quart, would it be a good oil for a brm?

Amsoil is overrated and overpriced. Use what works. Mobil 1 TDT

That's a good price....use it!

mobile 1 tdt is the same price that I can get the amsoil for and the amsoil also meets vw spec

Do you really think Amzoil is better than Mobil One??? Please, Amzoil is overrated, the only people praising Amzoil are those that sell it. Do you think Amzoil has the same labs, and scientists that Mobil one does, Amzoil is snake oil, praised by many of its sales men period, use are safer using Mobil one TDT, or Mobil One delvac 1

Read the literature more carefully. They crafted language that makes it sound like they meet the spec, but Amsoil does not apply (or pay) for any manufacturer certifications. They say the oil "is suitable for vehicles requiring 505.01" or something like that. There's no way of knowing if it meets the spec. It hasn't been certified.

Mobile 1 5w-40 doesn’t meet that standard either FWIW based on their product guide.

Don't think it does. But there are plenty of reasonably priced oils that do. Pentosin HP2, Rowe Hitec Synth RS DLS, Total Quartz INEO MC3, Liqui-Moly Top Tec 4100 are a few.

I know that a lot of PD owners use oil that's not 505.01 certified. I'm not questioning their decision. But my approach with my diesels has always been to remove any doubt by using oil that's certified as meeting the manufacturer's specification. There's not reason not to.

You'd have a hard time finding any 5w-40 oil that wouldn't be suitable for a BRM. That Amsoil formulation is quite good, but still a bit pricey at $6.75/qt, imo. You might look into the Delvac1 5w-40 rebate deals that come up regularly.

I wouldn’t use The new CK-4/SN rated Delvac 1 in any engine that has a flat tapper cam. Not sure if TDT is also dual rated now. Amsoil SS HD oils are better for this application.

Please don't drink the Amsoil KoolAid. If anyone approaches you wearing an Amsoil hat and jacket and randomly drooling and spouting Amsoil propaganda, run the other way!!!!!

No one approached me a local guy is retiring and closing up shop so hes selling his stock at cost to clear it out

A lot of guys were pulling their hair out when the CJ-4 rated oils first emerged too. Those fears turned out to be unfounded. It seems Ford is largely responsible for creating a distrust of the CK-4 spec. My understanding is that the Xw-40 CK-4/SN oils are exempt from the phosphorous/zinc limits that apply to the thinner grades. I'd wait for some UOA's on the PD engines before passing judgement.

It doesn’t meet the Ford powerstroke oil spec so the phosphorus has been reduced below 1000 ppm. Haven’t seen a VOA yet but the SDS suggests the D1 formula was significantly changed (with cheaper base oils) for the CK-4/SN rollout.

Interesting to note that many manufacturers advertised reduced wear, deposits, and friction with their new CK-4 products. Mobil made no such claims with the new D1 rollout. I believe the new formula was formulated with cost cutting measures and they took advantage of the new spec to cheapen the formula. It’s not an improvent and may actually be inferior to the old CJ-4 version while still meeting the minimum CK-4/SN specifications.
