Hi all
Just bought a Toyota Auris 1.33 stop/start (1NR-FE). The oil chart in the owners manual shows everything from 0W20 to 20W50 API SL or SM or ILSAC. It goes on to note that 0W20 is preferred as it provides optimal fuel efficiency, however if not available 5W30 may be used but should be replaced with 0W20 at the next oil change.
Here in the UK 0W20 or 5W20 is not easy to come by and costs $15-18/litre. I like to change the oil every 5000 miles rather than the 10000 service interval so I am looking to use a thin 0W30 or 5W30 which are a lot cheaper and easier to get.
My question is, what specs (other than SM or SL) should I be looking for as no ACEA standards or HTHS requirements are listed? I've purchased some Motul 0W30 Eco-clean SM/C2, which is a thin 30 weight (9.6cst), has an crazy VI of 235 and a HTHS of 2.87. I thought this was closest to the Eneos 0W20 (now unavailable in UK). Was this a good call?
Does this engine need a low HTHS oil to function correctly, or would a C3/A3/B4 oil such as Helix Ultra Extra or Fuchs Titan GT1 proflex offer better long term protection at a slight loss of mpg? Any thoughts gratefully received.
