Nothing else will have the exact same flavor of course, but there are other tasty oils out there. Some of them will either require a grocery store that stocks some slightly more exotic stuff, a trip to Whole Foods/etc., or some online shopping. Some ideas: toasted sesame seed oil, walnut oil, macadamia nut oil, hemp seed oil. Check the smoke point on any new oils you try before you do any cooking with them.
I haven't tried the macadamia nut oil, but I've read a lot of good stuff about it and it has a very high smoke point. Most of the ones I listed have kind of a mild nutty flavor to them.
