I cant believe how many on here chose Pennzoil Conventional or Pennzoil Platinum for cleaning since SOPUS pushes the cleaning aspect on the lube on the ad copy Ignore the garbage on the label except for service category and the approval list and/or the API Starburst. Dont be a gullible sap.
I think the Sopus products clean very well Arc.
I'm not so sure that they clean that well, at least when compared to other SN formulas. There are few people here that claim dirtier oil and maybe some slightly cleaner looking internals when looking from the fill hole, but these are rather unsubstantiated claims. For all we know, the same results could've take place with another oil brand.
So I agree with Arco that most people here just repeat marketing claims with no actual firsthand experience. Even with first hand experience there is no way of knowing what could've happened with different oil, as people don't have time and resources to do a proper comparison. They just go with most recommended oil here, which happens to be Pennzoil products.
This becomes a self fulfilling prophecy. The more one oil brand is recommended for cleaning, the more people are going to try it and the more likelihood that some of them will come back with positive experience even if the final result is negligible. This will make it look like the product cleans better than others without doing side by side comparisons or any actual testing that may not be favorable to the marketing campaign.
I’m not a marketing guru, but that looks a heck of a lot easier than actually delivering a product that meets the claims and proving it through testing.
