Engine oil PENNZOIL or MOTUL

SP certified oils have better LSPI protection than SN, and SP is what Subaru requires for this generation.

Prolube is trash used motul and my top speed increased by almost 10 on all gears on my d250

I've been running 8100 Power 5w30 for the last two changes, every 3000 miles, and the aced the initial Blackstone test.

I've been using the x-clean EFE every 3k miles forever now an am tuned on full e85 now for 30k miles besides the factory valve tube seal leaking they fixed at 14k miles once but that's due to 23' errors. Now am thinking did I use the wrong one hahaha but am 30k miles deep in my use never anything oil that the efe in mine.

I use PUP 0w20 in mine. Lots of tests and UOA show that Pennzoil Ultra Platinum is the best non-boutique oil you can buy. But honestly any top shelf oil will work. 5k km intervals are more important than brand with a turbo engine.

Using Motul (8100 5w-40 initially then 0W-40) since 8 years in my Honda City '09 and I replace engine oil myself every year. Engine is smooth and gives decent mileage. Never faced any issues

Upping your oil change intervals to 5000kms wouldn't be a bad idea. I use motul 5w40 and haven't had issues

Do her a favor a change the oil, with Valvoline Restore and Protect or Pennzoil Ultra platinum, it will quite down a little and it would be great for the car.

I used so many brands

- Motul : okay

Could be the oil and not any problem with the engine itself. In India, these engines come with Motul 7100 full synthetic oil. There have been some discussions on the 390Duke forums and on Reddit that the oil burning issue and high oil consumption is caused by using Motul 7100
