Got me considering ESP 5w-30 as it is now available at WalMart and AutoZone and others. I'd never probably go over 8k, definitely not over 10k on an OC. I'm not sure even if 10k is considered an extended interval.Grade for grade, the ESP oils tend to be more shear stable but not quite as long drain capable as the EP IMO. Mobil boosts the AO levels for the EP line for the extended drain. ESP 5w30 is more shear stable than Mobil 1 EP 5w30 and may offer better wear protection being the HT/HS is 3.53.
The Canyon and Silverado use an OLM. The VW actually calls for 10k OCI. The Mazda 3 has OLM and can can max out at 10k.
So to finish up if I were to use ESP 5w-30, seeing as it is a thick 5w30, would that pose any issues? Any effect on fuel economy would be negligible.
