Kirkland motor oil

Although the ambulance chasers are using the marketing of "obsolete" oil next to current standards as deceptive, in NM they did test the oils and discover the emissions control systems on many modern vehicles using the obsolete oil did cause problems with the emissions controls and may have damaged certain sensors. The long term effects are not know simply because there is no way to go back and test what had happen as nobody can say for sure what they sued last year or the year before. So, it's all based on what can be tested now.

Ignorance is bliss (so they say at least) until you have a lubrication related failure. Then you'll change your tune.... as your wallet gets emptied.

Show me any documentation that the use of one oil over another, with regular oil and filter changes, caused any engine failures.

You're right, there aren't any.

Well there was the more recent issue with oil sold at cheapo places that did cause engine problems. The courts have agreed to combine all the various lawsuit all over the US into one class action from one major retailer who sold that junk. Although oil may be oil, SA or SB rated oil should not be used in vehicles manufactured after the 60's but it's still being sold at stores all overt the US to ignorant people.

An example of a cheapo place? Business name? Oil brand name? What was the damage to the engine? Sorry just my skepticism from my 30 years as a cop that I like to see proof of some sort.

Dollar General, house brand. No real damage to anything. More of a case of they sold oil and people did not read the specs on the bottle but looked past it at the cheap price. The claim was Dollar General is at fault because they put it on the shelf next to motor oil that did meet newer specs. Just a case of someone smelling a payday because somes people are cheap morons. You sold cheap oil and put it next to the Quaker State, I did not read the label, so pay me LOL.

This is interesting. I also have sent in sample of off brands synthetic oils after 5000 miles and the results said the oil was close to being new. All of these oils are made by major oil blenders.

I have sold private label products for many years and there is no way that Costco/Walmart or any of the other major retailers are going to sell a private label product that doesn't meet or exceed the quality specs of the major brands. Same product that came out of my factory had multiple labels - prices/advertising budgets varied but the product was essentially the same. Think about it - big retailer has significant leverage on mfg and there is no way he is going to put his name on product if he has exposure.

Kirkland/Costco doesn't manufacture or blend oil. They buy blended bulk oil from those who do and package it in their own proprietary containers. Costco brands, IMO, have always had my respect as far as quality. (they aren't perfect) 10 quarts of synthetic oil for $2.50/quart is a good price provided the oil meets the specifications (in your owners manual) required. Any quality oil, synthetic of not, will have the specifications it meets written on the container. (API, ISO, ACEA, etc.) You can always pay more, if you want. It is your responsibility to confirm that the oil you purchase meets/excedes the requirements of your specific application. In short, you have to decide if good, . . . . . is good enough.

If there is one store that has earned my loyalty, it is Costco. I trust their marketing and packaging departments have done their homework and are offering a quality product at a fair price. If they offered a 15/40 diesel blend I would change in a heartbeat. However, their chicken seems to be overpriced!
