My daily driver always had 5w40 or 10w40, decided to try 5w30 and it burned a bit of oil during the first 2000 kms after the change and now consumption has completely stopped for the last 5000 kms. The little 4 cylinder seems quieter on cold starts and maybe slightly less sluggish (i still think it is a placebo). I want to continue with a 5w30 for at least the next oil change but my choices are limited. The only full saps A3/B4 5w30 available at the stores is Shell Helix Ultra. Is there an alternative i can buy online for a good (better?) price? All the 5w30 at the stores are low/mid saps and the specs are API C3, MB 229.51, VW 504/507 etc unfortunately and they're more expensive too.
