But can they remain top-notch oils, iof they need to someday conform to SN Plus and Dexos1Gen2? That would require them to offer weaker add-packs..... right? If they add/beef their base oils, isn't more PAO frowned upon by LSPI doctors? Aren't 50% of vehicles made today TGDI/GDIs? So how do the boutique oil manufacturers stay far ahead of norms like Pennzoil, Valvoline and Castrol.... among others and meet SN Plus Dexos1Gen2??

IF Red Line offered a (MUCH) reduced calcium (and sodium), much greater magnesium content oil, within my needed HTHSV spec range (but all else being equal with their current add packs/base oils), I would use it in a heartbeat, despite it not being D1G2/Ford 945B 'certified'.

I think these oils are meant for two different usage patterns. Redline is more for high temperature wear protection. AMSoil SS is more for long drain intervals. I have run Redline many times up to 8000 miles, and it does fine. AMSoil is more for 15,000 mile drain intervals. What more suits your needs?

How many miles on your truck?
Do you tow or haul heavy very often?

The OP had to repeat what his two options were at the top of page 3 and still you insist on Walmart choices!
Ian, go with Amsoil Signature series for a daily driver.

Nobody here ever talks about the science anymore, not even the basics, rather funny. What is modern Amsoil SS? Low viscosity, low additive oil made for di turbo's. What is redline, high viscosity high additive oil made for older style v8's or over built high taching non di engines. Go to Ram forum, the log term uoa's on redline have been as good as anything. Not knocking Amsoil, it is what it is, it is an oil built or should I say re-formulated for modern engines, but the hemi is far from a modern engine. If you believe in one oil can satisfy every application, then go for amsoil. BTW, ram forum top 4 oils used, Pennzoil number one, m1 number two despite not having or recomending it for the ms6395 spec, amsoil, and 4th is redline 5w30. People that have hemi tick over there bar far choose redline, w/o hemi tick Pennzoil PUP/PP is tops.

Yes, I am very disapointed they don't make a lineup that is di sn+ friendly. They got on board with low ash with their newest oils, but still left the largest part of the market out of their formula with this bad decision. Your right, if they had low calc/high mag with that zddp/moly ester/pao package, that would be the darndest oil around. 50% or better is going di, I can't believe they havem't made the switch, they loose nothing by doing so. very disapointed for folks have a di

I don't know if this has been posted before. They talk about polymeric thickeners about halfway through. For a modern daily driver I'd use Amsoil. Redline should keep the Ester/PAO formula as is, but make a more modern additive package that doesn't have the ZDP/Ca levels and overall higher SA. I wouldn't use this oil due to the LSPI issues.

Dear Pablo,

Quick question:

My car calls for VW502 00, OCI: 1 year / (15000KM)
Would it be OK to use Amsoil SS 5W-30?
PS: UOA is relatively high price in my country ( ~75~80 USD)

Many thanks.

David

What car? What year? How many miles?

I think some of guys should have read posted date before recommend to OP lol

Amsoil has been good for me in the last decade I have been using it. Allowing me to go further between oil changes with the massive amounts of miles I drive weekly. 300K miles on my Santa Fe with 0 consumption when a defective camshaft let go. So they know what they are doing compared to other brands. If you decide to go that route you can use it with confidence.

I've got it in our families vehicles as well along with the ATF's.

It's up to you, just wanted to share my experience with the product.

It’s a 2017 Skoda Kodiaq (26XXX KM so far).

(gasoline EA888 gen3b. 2.0L, Same as 2018 VW New Tiguan)

and pick the 0w-40 one, preferably. You could pick any one of them.
Amsoil SS 5w-30 has an HTHS that volkswagen says is too low. VW 502 says you need an HTHS 3.5 or greater.

The HTHS numbers are higher on the Amsoil XL / OE series oils and they are less expensive. Just in case you want to add that for consideration.
