Engine oil MOTUL or AMSOIL
My N54 hated any variant of Mobil1 sad to say. When I had American vehicles they all seemed to love it however. Currently running Motul 300V on a FBO, occasional E85 mixed N54 and wish I used it from day one.
2016- 130k miles and counting. Stage 1+ tune (Bren tuning). Clutch @ 90k. AOS is great. Motul oil every 4K miles- get the fumoto oil drain valve to make it easy.
I do Motul @ 5k.
I’m at 133k with no weird noises, knocks, etc.
I do 3k with Amsoil SS as well. Blackstone analyses of TBN show I could easily do 5,000k.
for my Focus mk1 2002 1.6 i use Ford motorcraft at the last 2 changes but motul 8100 is totally fine, prev owner used it for 50-60k kms without issues(i know the owner, the mechanic, and i got a huge pile of paper as service history). odo is close to 280k. oil consumption is 0.5-1.0litre / 10000km depends how heavy my shoe is on highways. most important is oil spec and visco. any “good named” brand from valid source will work perfectly. i prefer motul and eneos, but this is just me, they do exactly the same: works no question. just change it regularly. i do mine at every 10-12k but i commute to work 100km 4 times a week, my oil barely operates cold.
I use Motul 300V Power 5W-30 Engine Oil w/ESTER Core Technology. I have zero complaints.
I use Motul 300V Power 5W-30 Engine Oil w/ESTER Core Technology. I have zero complaints.
I've been using Motul 5w40 for years and years with zero complaints.
I run 10w40 5100 motul now. on all bikes etc.
Clutch doesn't like the full syn stuff.
Amsoil's biggest 'benefit' is a longer service life. Their additive pack doesn't break down as quickly, so you can run it longer between oil changes. However, if you're paying twice as much and running it twice as long, it's a wash and you're not gaining anything. When I was selling Amsoil, I had a modified 4 banger and a high mileage 24v that had both been running Rotella for the entire time that I owned them before switching to T6 when it was introduced. I pulled UOA samples every 1k miles, then switched to Amsoil Signature after 5k and did the same thing except I pushed the Cummins to 10k. Zero improvement in fuel dilution, wear markers, or carbon build-up. After seeing there was no real-world benefit, I stopped selling it. I won't market a product I don't believe in, let alone one that I see as an outright scam.
