i'm not into tuning or modding-- my mechanicals are stock, and i've got minimal interest in changing any of it besides installing ITB's for the sound characteristics, maybe. my interest is really just engine longevity, despite the fact i love ringing it out and bouncing off the limiter.
ignoring the overall costs of the options, (lucas' product is $20-some/quart), is it better to run a thicker oil like 5w-30 to make up for the lack of oem oiling? or is it better to run something like lucas' product that makes 0w-20 'sticky'?
is there a better third option?
or is it 'good enough' to just run 0-20 and figure it all out later?

I'd say stay away from Lucas. Stick to your regular oil and just keep it going. Bouncing off the redline isn't an issue with 0w-20. Doing it at high oil temps on the other hand, might be. So if your driving habits constantly bring your oil temps up, I'd switch to a higher weight oil, but no more than 5w-30. The best you can do aside from that is just be mindful of oil temps. If you smack the redline a bunch and the temps creep up, start shifting earlier (like 6K) or calm the driving and let the car cool down a bit. Then you can do it all over again! I can't guarantee these habits will help extend your engine life... but they are likely to help when it comes to our platform.
I've tried Lucas in the past for other vehicles. From my experience, it does more damage than good. In the short run, it looks to help. But in the long run, it expands problems further. I could be wrong with that as maybe there have been many other success stories with it. I simply agree with the logic to stick with the stuff the car was designed for.
