Amsoil Signature Series vs Motul 300v

What vehicles do you own?

2021 Silverado
2023 Rav4

50% street, 50% track.

Depends how often you track. New 300V has more PAO and less Ester. It oxidizes less, so it is bit more suitable for street.
In reality, any Euro oil will do it. If you want to save money, get any oil that carries MB229.5 and Porsche A40 if you track.

I guess the new oil can design isn't just for show. Interesting data!
What would be some prime examples of oils that contain 'MB229.5 and Porsche A40'?
How suitable is the Amsoil Signature Series for my use-case?

Nice cars! What exactly is the tier list for Amsoil?

OE -> Euro -> Signature Series -> Dominator?

OE > OE XL / Euro > SS

Dominator is in its own class. It's a racing oil. It can take a few thousand miles of street time, but not much more than that.

If you are dead set on Amsoil, go their Euro stuff. Euro stuff is always more stout.

Do you have any data to supply that directly compares 300v vs Signature Series in terms of performance, wear, etc? My driving consists of daily driving, AutoX, and Tracking and I've been running 300v in my boosted 86 for the past 2 years for autox and daily driving. But now that Im in a stock NA GR86, I am considering saving some money and going down a tier to Signature Series since it's much much cheaper.

I can only do so much… I’ve never seen a value proposition that justified 300V; not saying there may be some cases where it makes sense, but I haven’t seen them. I run the Gear 300 for 50k in Subaru transaxles and diffs and never had an issue. However, I’d have zero reservations running Amsoil SVG for the same interval or HPL Gear Life for double that. If you look at my diff gear oil change, I put HPL in at 75k vehicle miles, and I may pull a sample at 150k just to check in.

The bottom line is, gear oils today (esp the J2360 approved gear oils) are so good that consumers need not fret; pick one off the QPL and don’t worry. Don’t necessarily choose based off my experience, because it’s just one data point. The J2360 QPL is a no-brainer list that delivers proven performance, but you can also use my 75w90 threads to choose among the gear oils I’ve had tested.

Interesting how you guys are saying race oil is not very applicable to the street. Where I come from, most track and street drivers use race oil (300v) to preserve their motor's longevity and performance.

Got any data to back that bolded claim up? I’d be willing to bet even money it will go further than you’d imagine possible.

Yes I too run the Motul 300 & 300 LS for diff and trans. But I have ran Amsoil's variant for diff and trans fluid before, and it seems like the Amsoil is much more smoother especially when shifting in cold weather.

Oils like Dominator or Driven's XP line have a lower total base number than most other oils. They aren't designed for long OCIs.

Street oils are tough! Tougher than race oils in what they are designed to do: short commute, cold starts, oil not reaching operating temperature etc. It is not all about wear, but deposits, oxidation etc.
i have on the shelf some 20qt of 300V and use it strictly in the summer when I track BMW.

I’ve only used Motul Gear 300 in Subarus, because at the time it was one of the only GL4/GL5 dual rated oils. These days, HPL is dual rated and has better performance so I’d default to that. Amsoil has always performed well in whatever it’s been “recommended” for.

Lower TBN for engine oils does not always mean shorter OCIs in these days of low-sulfur fuels.

So you would recommend HPL for Trans and Diff oils?
Interesting.

Interesting.

Their formula exceeds GL4 while also being yellow-metal safe like GL5 requires. Their gear oil used in Richard Petty’s Cup cars picked up 7.8 horsepower over M1’s best offering on a $15M chassis dyno… and when Cup cars are spending upwards of $100k per HP gain on restrictor plate engines… 7.8HP for ~$15/qt is the steal of the century!

So Dominator is essentially the Amsoil's version of 300v?

HPL?

You do realize HPL supplies race oil.

Used in NASCAR, drag racing, pro stock, world of outlaws, offshore boat racing, and whole other bunch of venues. If being used by racers is your standard, then HPL is the best.

Further, and I think this point to be very important, they do not pay for racers to use their oil. All of the teams that use High Performance Lubricants oil actually buy the oil from High Performance Lubricants.

So, unlike a lot of teams that have oil company logos on their cars because the oil company paid them to put the logo on there, High Performance Lubricants is different. The team put the logo in the car because they purchase the oil and it works well for them.

As others have noted that's not what race oils do. Kind of like more is not always better.

Or "used on the Space Shuttle" or "used by the military".

And as far as your opening post, there is no best. People ask that all the time but you cannot distill every aspect of every oil down to some comparison ranking under every circumstance and use.
