I have my reasons, may not be solid ones, but they are reasons none-the-less. LOL I'm currently doing 3K/3 month OCI's with Mobil 1 EP/Valvoline EP 0w20. Was going to switch to Mobil 1 ESP 5w30 keeping the same 3K/3 month interval. So by moving to 4k/4 month with HPL, it will actually cost me a bit less $$$ vs ESP 5w30 at 3K/3 months.
My main thing is with GDI and carbon deposits on the intake valves. My hope is that with keeping the oil fresh it may help limit IVD's over the long term. Will it? I have no idea, but seeing it's oil vapor that's being deposited, my thought is it may help. If it doesn't, well. it won't hurt anything besides wasting a little bit of $$. I'm also hoping switching to HPL will also help in addition to a 5w30.
