The only full syns I know of in a 10W-40 are Amsoil and Redline. Redline also has a 5W-40 available, but it's harder to find. Another consideration might be Mobil's Delvac 1, which is a 5W-40 as well.

Others will probably disagree with me, but a high quality 5W-30 or 10W-30 should hold up fine, and I wouldn't go to a thicker oil unless you were seeing indications of a problem. Thicker is not always better.

Don't forget I have a built engine with 9-1 compression, heavier valve springs and a JWT cam and the rev limiter set a 7200 rpm and I occasionnally use a 65 shot of N20. I have an egt sensor placed at the Y pipe junction and I routinely register 1200-1450 degrees that far from the exhaust manifolds. Also I live in vegas so the bottom line is my car can run very hot when I rod it and an oil like a 10W-40 redline syn. should be beneficial. Am I missing something??

I'm not a big fan of Royal Purple. Most of the feedback on their products comes from people making claims without any data to help back them up. It might be great oil, but I see much more information on Amsoil and Redline than I do on RP. Not knowing much about RP, I would say that the safer bet is staying with either Amsoil or Redline in this case. Those oils should be more cost effective also.

I'm agreeing with Mark here, I have yet to see an impressive Royal Purple oil analysis, especially in its racing form.
My recommendation:
Use a 10W/30, either Amsoil or Redline. Both will serve you well. Both retain their viscosity range, won't shear down significantly, and a 10W/30 will tend to stay higher in a 30 weight viscosity range than a 5W/30 would.
Even given your conditions, I'm not convinced a 40 weight oil is necessary. For a xW/40, I would go with Mobil 1's 5W/40 "European" formulation due to its availability (any AutoZone will have it) and its more rigorous testing standards compared to Mobil's SuperSyn formulation.
More importantly, you should consider at least periodically taking an oil sample and having it analyzed. That will let you know better how your oil changing has affected your engine than anything anyone here could speculate.

Car: 97 Maxima 5 Speed Manual
Mileage: 120,000
Oil Used: Castrol GTX 10W-40
Location: Southern Mississippi
Driving Habits: Fast Acceleration
Mods this month: Warpspeed Performance ypipe,bpipe,
Question: What are my oil recommendations? I plan on changing to Redline Syn 10W-40 is this a correct decesion? At this point what should I select? After reading the post I wanted to make and educated deceision considering my driving habits, location, engine mileage and the exhaust mods I will be getting in a week or so.

Ron, using a racing oil, from what I know, is not a good idea in a stret car because the detergent package is minimal, street applications need detergents. I use RL 10w30, it seems to be doing just fine, I have done some oil tests and its doing good, better than Mobile 1. I am considering switching to RL5w40 in a few oil change intervals to see if it helps or not. I'd say give RL10w30 a shot for a few oil changes, I go 6k with good results with RL. If that dosent help try the RL5w40 or RL10w40.

Oil in my 95 GLE auto
I have just over 100Kmi on this car and it seems that by 2k mi after an oil change, my oil gets very dark. I don't use a particular brand. I know the mechanic puts in the right amount and it's 10w30 non synthetic.
Any suggestions to prolong my oil changes?
