Default What oil is everyone using for their ISF change?
Im sorry this is another oil thread. I tried searching but just want to hear what oil everyone is using.

FYI my car has 104k miles and has had synthetic oil changes since 12k miles. im 1,000 miles away from a oil change and I want to get the BEST oil possible!

"Best" oil is always up for debate and preference even with all the oil analysis. I've stuck with Mobil 1 5W-30 regular or extended from Walmart every 5k miles depending on whichever one is on sale.
I've also tried Royal Purple, Amsoil, Redline, Toyota, Liquid Moly, and there's really no difference in terms of "protection" for street driving. As long as the cooling system is in working condition and oil changes are at recommended intervals, I doubt any oil will make a remarkable difference. Plenty of 150k-300k+ mileage ISFs on the original engine, so I think even 5W-30 dino oil would even be sufficient.

I've used royal purple hps and now Amsoil signature series in conjunction with their engine flush and their fancy oil filters.

Just got my F and the oil was changed before I picked it up. Most of my cars I've used Mobile 1 or Amsoil with correct weight and Mobile 1 filters. DO NOT USE FRAM FILTERS! They're terrible! I'll probably go with Mobile 1 5w30 and an OEM Lexus filter for the F.

The MR2 gets Valvoline 10W-30 VR1 Racing Motor Oil and Mobile 1 filter.

For what it's worth, I use Pennzoil Ultra Platinum, Since I live in a hot climate I use 10W30. For a filter, it's a WIX XP filter.
