Hmmm, I'm thinking Anecdotal, Empirical, or Unintelligible. Of the three I'll take the third.

Redline is good stuff. The rest can be replaced with hydrocracked formulas, and at great savings. I'm ducking, but fire away if you will!

redline is good oil. the valvoline was the oreilly's free after rebate. bought a jug of valvoline syn at wmart-some of free oil left from the case-for next change, and even though it works better than the mobil 1, really felt under max throttle fully loaded, the redline was noticeably better. ~2+ gals of gas (today)equals 1 qt of redline, but by the cases the SI-1 was discounted quite a bit by a local performance shop. engine warranties seem to gnaw at some peolple (starburst, approved), even for products sponsored at bob's - the famous first syn oil.

My experience with Redline was some years back, and I used it in a Harley-Davidson 80 inch twin. It was great stuff for the Hog. Since then, the price has gone astronomical on Redline and H-D!

Don't think redline existed when a bmw R69s/US with a good spring loaded solo seat was under my behind-how do they ride bikes with a thin seat on the backbone. Think heavy dino was used.

Recently changed motor oil in 2000 VW bug. Engine contained standard (regular) motor oil, and it hadn't been changed in 2+ years. I put in a 5W40 synthetic. Car is now running very sluggish and knocking a little. Any thoughts?

The changing of your oil may simply have been a case of too little, too late. Your engine may already be toast.

OK, thanks for your reply.
 
More information: after changing the oil, I checked and re-checked the oil level. While doing that, I cracked and broke a part of the dipstick tube, which is plastic. We got that replaced the next day at the VW dealership. While at VW dealership, we also asked them to check on why "check engine" light was always lit. They did check on that and fixed it so it was no longer on all the time.
 
Then, next day after leaving, engine became very sluggish all at once. Because of this sudden onset, I'm thinking it wasn't just a coincidence of long-time neglect.
 
Your thoughts?

During the two years that the oil was not changed, was it being driven or was it in storage or something?

It was being driven, probably ~10k miles per year.
 
I emphasize that engine was very sluggish, but not knocking.
 
Spun bearing? In any case, it's at the garage and will have a diagnosis soon.
