GreyBrick Posted August 3, 2007 Share Posted August 3, 2007 (edited) Have any checked with a service manager to see if Nissan has a specific recommendation for either a low or high HTHS (High Temperature High Sheer) value in the 5W-30 API SM motor oil as required for the VQ40? Also I'm looking at running an ester type oil such as Redline or Motul and wondered if there could be any problems with that other than a lighter pocketbook, I'll be doing normal period oil changes and not extended. Thanks. Edited August 3, 2007 by GreyBrick Link to comment Share on other sites More sharing options...
94extreme Posted August 3, 2007 Share Posted August 3, 2007 best place to check for that is your onwer's manual. if you go with redline, why change it so often? it is designed for a longer change interval.. same with all the synthetics.. otherwise save your $ and go with conventional dyno oil.

Thanks Mz, no info in the owners manual other than API SM and 5W-30 but the local dealer (Calgary, Canada) says that the factory fill for the Canadian PF's for this area is Esso Extra which also doesn't specify an HTHS so maybe that designation difference is more for Euro vehicles.
