Sure, other oils might make it that long, but some shear down quickly and none retain their TBN as well. Besides - when I started using this oil with extended OCIs over ten years ago it was the only oil on the market that could last that long. I have 317,000 miles on my car, and it still runs like new.
Hi Kuato
Looks like like long drain is working for you. Are you able to provide brief details of the savings made compared to the usual OEM OCIs for your vehicle since you started.
Check with slalom44; he's the one doing the long intervals.
