Interesting, so what are the factors one need be concerned with if they elect to run the 300V on a car thats track and street, always garaged, I'm fine with the shorter intervals/higher running costs. is it fine for 500 cold starts?

You should not see this being used any car that isn't a dedicated race car at all. How many race-only Subarus do you normally see? I've only seen 2 around here. Also, Joe Gibbs race oil is not similar to Mobil 1.

For you're car? Anything's possible. :D

Also, loaded question, you already know the answer.

Hmmm. I was contemplating tossing in some 0w-30 euro spec mobil 1 i have left that was intended for my old A4. Whats wrong with mobil 1?

Yeah, not at all similar.

I don't know of any dedicated subaru race cars locally.

The only problem I have with race oils is that our race car burns way too much to afford them lol

Could you please elaborate on that?

This is a good read.

We've been doing oil changes on Subies for 10+ years.

Over that time we've done 6,000+ oil changes on Subies.

We've found Mobile 1 and Subaru Synthetic to consume the most amount of oil between changes, on average about 1Q per 3,000 miles. While Motul 8100 C3 X-Clean 5w30 and Amsoil 5w30 both generally go 5,000-7,000+ without consuming any oil or <1 Quart and still yield great blackstone results.

Up here we have lots of dedicated Subie race cars actually :)

I agree though that you need a balance between a good protective oil and what is fiscally smart. Similar to using less expensive rotors since they are considered a wear and tear item on a track car.

Have you guys been using the Amsoil 5w30 Signature series? I plan on running it with a 5k OCI, i went with it over the motul as I get it for about 60% of the cost of the motul.

We've been using and are an Amsoil dealer for about 9 years. The 5w30 Signature is what we use in conjunction with their extended life oil filters. Very good results via blackstone and our own ad-hock testing. If you get it for less than the Motul cost, then use it. We sell a lot more of the Motul these days because our cost on the Motul is much less than that of the Amsoil and therefore our customer cost is also that much lower.

Thank you for the reply. I was actually referring to the motul 300V for the increased cost instead of the 8100. How would you compare the 8100 to the amsoil?

Disclaimer: I have never had a uoa performed. I am basing my following comments from the little reading I have done about oils from the internet. So much information!! Some of it true. Please bear with me.


I am suggesting that Mobil 1 was no good in that engine. I have read a few times that there is no "best oil"; different applications respond differently to different oils.

You are saying that Mobil 1 is consumed at a higher rate than other oils in Subaru engines. How would you rate it's lubricating/anti-wear abilities?
Besides the expense of having to add oil on a regular basis is high oil consumption indicative of anything else?

Thanks for the education.

We like the 8100 as well as the Amsoil, for our purposes we feel the Amsoil is great for extended OCI >7500 miles. The Motul comes back with great numbers with 7500 mile OCI.
