Hi I have a 2000 Toyota Rav4 with the 1AZ-FE engine. 75k miles and it does mostly short trips every day. The manual calls for an "energy conserving" Ilsac 5w30 (or 10w30). It runs fine except for a puff of smoke in the morning which I am not too worried about (stem seals I assume)
This maybe an Australian thing but dino 10w30 is much cheaper than anything 5w30 but tends to only have SM Ilsac ratings. 5w30 maybe either ACEA A3 only or Ilsac with or without ACEA A1/A5. I have no interest in the fuel savings of Ilsac oils. So ideally what is the best type to choose? Are the straight SM Ilsac oils all I'll ever need or will I benifet form using something with an ACEA rating?
The family also has 2 older Nissans with the SR20DE engine (Nissan spec 7.5w30). A 91 and a 97. Pre Ilsac I assume. Can I use a 10w30 SM Ilsac oil in these or should I go for something with an ACEA rating? I've been using 15w40 untill now. Thanks for your time
