No. Rotella T Syn is comprised of 70-80% XHVI with NO esters or PAO. Helix Ultra has about 10-20% XHVI with the rest of the base oil being PAO and esters.quote:

Isn't Rotella Synth the same basestock with more additives?
Base stock depends on Helix Ultra grade (see links):quote:

Helix Ultra uses a mix of PAO, esters, and XHVI (Shell's proprietary Group III wax isomerate). You can get it in North America at Ferrari dealers—just be prepared to pay anywhere from $20.00/qt (0w40) to $60.00/qt (10w60). These are the only two grades imported.
That deserves a couple of these also...quote:

Believe 15W-50 is one of the best, but it is not available even in Spain with their hot climate.quote:

Hi,
Shell Helix Ultra is an extremely good lubricant with a great reputation
Shell have been manufacturing synthetics for a very long time - for engines and driveline
My first use of their diff and gearbox synthetics occurred about 25 years ago
I have used Helix Ultra for at least a decade in a variety of engines. From ride on mowers to a Porsche
UOAs for this oil in my Porsche have been posted here four times
I believe that Shell's XHVI base stocks are used by other oil makers too
Regards
John, I don't have the RL. I sold it. My wife's car is on Amsoil and I've used both Amsoil and M1 over the course of 138k miles. RL is expensive for me and I have a pref. customer rate with Amsoil so I wanted to take advantage of it. I'm going to start using just Amsoil/Mobil 1 in the future for cost and availability reasons and the fact they are very similar. I also think these might be better extended drain oils and this winter I really want to get away from changing it often. I still believe RL will prove to be a great oil. I do sometimes wish I tested in the Corolla bc the engine is very clean. Sorry.quote:
buster, Do you have a quick link to A3 spec.? buster did you ever decide if you were going to keep the case of Redline you bought? I am asking out of selfish reasons really. I am trying to get as many people to try Redline as possable to get some data. I am especialy interested since it would be going in your trusty Corolla! Thanks!
P.S. How does Redline 5W30 and Amsoil 5W30 compare in reguards to A3 spec.??
