Some oils are group V based. And seem to offer good performance in many areas. Cleanliness seems to be a strong point for Esters. Redline comes to mind.
Other oils are Group IV based, and seem to offer very strong TBN retention as well. Amsoil and some Mobil grades come to mind here......
Some oils are a group IV base with a solid dose of ester(s) (some Mobil 1 grades) which seem to offer a good mix of both things: Good cleanliness with a strong TBN like M1 TDT, 0w40....etc.
How they will perform in YOUR situation though..... You won't really know unless you test. One thing I've learned on here: The best oil for MY car may not be the best oil for YOUR car. And choosing an oil based on it's base-stock is not a wise-move.
Some observations (and hijacks from other posters):
-Redline doesn't handle fuel dilution well.
-Mobil 1 0w40 sheers like a bugger, but still performs very well.
-Redline, Mobil 1, Amsoil, Rotella....etc. seem to keep engines very clean. I can vouch for M1 and Amsoil first-hand on this one. No experience with the other two.
-RLI bioester oils seem to handle fuel dilution phenomenally well based on a saga that is documented in the UOA section.
Keep in mind: My first-hand experience is limited (primarily) to Mobil 1 and Amsoil. Not to say I don't have experience with other brands (I do; Castrol and Valvoline primarily) but that these two brands are the ones I've used the most and recommend based on my experience with them.
