What Oil weight do you run? - Page 3 - Toyota Yaris Forums

Some info about RTS 5w-40 WAX Synthetic:

Shell Synthetic is made with Shell's XHVI base oil, which unlike other Group IIIs does not begin as distilled crude oil, hence of all Group III base oils, XHVI is truly the only one that can legitimately be called "synthetic." XHVI is a wax isomerate, meaning that it is made from the slack wax removed from distilled crude in normal solvent dewaxing. This slack wax is catalytically transformed (isomerized) and hydrofinished into a chemically pure base oil which rivals PAO in virtually every category. There are other "synthetic" oils out there based on Group III, but Shell's is unique in that it uses XHVI base oil. Chevron and Petro-Canada produce Group III base oils that come close to XHVI, but even though these oils are all hydroprocessed and utilize the same type of isomerization technology employed in the making of XHVI, they are not the same thing. Only XHVI is made from pure petroleum slack wax and its CAS number is 92026-09-4. The CAS number for the more typical all-hydroprocessed Group III base oils is 64742-54-7. If you want to know what your "synthetic" oil is made from, take a look at the MSDS and look for these numbers. ( One CAS number for PAO is 68037-01-4).

In brief, don't be so quick to dismiss Shell Synthetic as just another "synthetic pretender." It's made with the same base oil as Shell's Helix Ultra, and everytime you see Ferrari win a Formula 1 race, that's the oil in the engine.

so I take it that SHELL FUll Synthetic 5w-30 and their other weights are a good thing ? If so , thanks for the info . How about the regular PLATINUM , the new ULTRA , and the newbie EURO ? Thanks

Pretty for sure there won't be a UOA on the M1 0W30 that I'm running now because the Yaris might already be sold; the guy is still thinking about it. If it sells I'll probably get a '08 xD that I've got my eye on...probably won't mess with sending in oil samples for the xD.

I use 20W50 semi synthetic.
What do I get by switching to 5Wanything?

This is a real hot country with summer temps at 45 Deg. C. Plus starting May on.
