Engine oil MOTUL or AMSOIL

Think the last oil change I did was with Motul 7-series (fully synthetic) 10w40 because central Italy gets HOT

I've recently switched to Motul because the Castrol pouring spouts seem to have gone away and Motul's also become more available.

I've put whatever motul 10w40 semi I can get cheapest into my blackbird every 10k miles for the last 140k and it's fine.

You can use Amsoil just fine, one of the best oils on the market.

In Florida, I use Motul 300v 5w30 for track days and tuning. Otherwise I run motul 8100 (5w30) if I know i'm not going to drive the car hard for awhile. I change the oil pretty regularly because it's a simple insurance. Always send the oil into blackstone to test.

I\u2019ve been running Amsoil signature 0w-20 in my FL5 for about 5k miles now. No track driving, just a mixture of city/highway. Some spirited pulls and rowing through the gears but mostly normal driving. Car is stock aside from PRL intake and custom tune. Had Blackstone do an oil analysis after the first 3k miles and all was well and below the average for all wear metals. I\u2019m in Florida so pretty hot climate overall. Very happy with the oil and will continue to use it at that viscosity

Take it from someone who's owned a gen1 since new. Motul300v full stop is the good shit. 200% worth the cost.

motul 5100 here in thailand is recommended.

I have amsoil in mine. I went 7500 once. Im sure anyone can go 10k with amsoil but it will be dark oil when u change it out lol

I used the Motul 10w50 fully synthetic. After running it for a few months I happened to check oil level and I was shocked to find out that 500ml had disappeared. This never happened on the stock Royal Enfield oil, nor with the Motul 5100, so I was not used to keep checking oil level religiously. But now I do.

Then I checked YouTube reviews to see if others report oil evaporation or burning off. And yes lot of youtubers report it, but still recommended it!

How can you recommend an engine oil that evaporates or burns off, even if it gives slightly better performance? It's ridiculous.
