Engine oil Shell or MOTUL

Motul 8100 xcess for high mileage. I've had a few subies thrive on this stuff.

I have a 2001 Forester L and I enjoy using Castrol Edge 5-30 during winter and Rotella T6 5-40 during the summer in Arizona.

I’m on rotella t6 on my ‘05 Impreza at 217k miles. Just had all the seals replaced. It has been on rotella since 132k miles. Runs really good.

I live in a dusty climate I change my oil at least annually and I use Mobil one in my Volvo, Kirkland synthetic in the kids cars, and rotella in my air cooled vw.

I only use Motul in my car, but I only drive enough to really do 2-3 oil changes a year in 3000 mile intervals usually.

I use Rotella T6 5W40 on my stock motor STI.

Did switched my D400 to Motul 7100 4T 10W-50 @ 8K kms but in a non Bajaj service center.

Difference that I notice:

Engine looks a bit refined and smoother at high speeds or cruising above 70.

On my newer engines that are modified I use motul, older high performance flat tappet engine I use rotella or equivalent. On my daily commuter I use castrol.

Better than other 5w30 engine oils that I have used. Do not need to add oil between oil changes. Super smooth.

Nothing wrong with LiquiMoly, but I personally find Shell Rotella T6 to be better. It is quite a bit cheaper as well.
