Lake Speed Jr started my paranoia with his "when you shouldn't use Mobil 1 0W-40" video. I now recognize the concern is not applicable, especially with API SP. I'll continue to use Mobil 1 0W-40 FS without concern.
Cheers
Just wanted clarification with any potential concerns with Mobil 1 FS 0W-40 and LSPI with its higher calcium levels.
If I use 93 octane Top Tier fuel and 5K OCI with my 2018 Audi A5 is this an issue?
Thanks in advance.
