Does anyone here on this site change their oil every 3,000 miles or three months with syntheic oil?I was at the Castrol site and they recommend 3,000 mile/3 months OCI even with synthetic.Do other oil companies recommend the same OCI?Thanks Joe
Does anyone have any guess as to the what and the when the oil change industry is going to start talking the truth, which apparantly is that 3000 mile OCI is unnecessary far more than it's necessary? They aren't doing a caveat that 3000 mile OCI is for severe service, they're pushing the old school line developed long before the oil technology and metalurgy of modern times that EVERYONE MUST change their oil every 3000 miles. There you have it. And that's only one element of the oil change-industry, the oil companies. On top of that, you have the quick-change shops, dealers, parts stores and filter-folks all drumming the same false concept into the heads of consumers who know no better.quote:
I've been a 3000 mile OCI'r for my whole history as a DIY'r with M-1 and until a year ago, Frams. Fact is, the oil was so "dirty" in my last car (it was a very clean running Hyundai 1.6l 4 cyl with 160K) that I felt compelled to change it. Before BITOG, the concept of long OCI was alien and unfathomable, but that's marketing, I guess. The oil is "dirty", so you change it, right? What did I know? What does ANYONE know that doesn't find a venue such as the BITOG?
However, the oil, oil filter, and quick change industry simply isn't going to promulgate the idea that the oil isn't really so dirty after all, and of course, we here know that it's really just getting warmed up. So, outside this venue, how does the rest of the oil-changing world get the word? From reading here, I've reformed my opinion (and OCI-related behavior) based on the testimony (and UOA) of a lot of folks in the know that reside right here and nowhere else.
So, hereafter, in my new car I purchased, it's 7500 OCI with M-1 Syn with a dask of VSOT, and no more Frams. This dinky little Hyundai I just bought isn't stressing the oil on any level, so I hear, and I would be happy to go 10K, and may, based on 7500 mile UOA that I'll run. If I get a good TBN number, I'll go longer. The fact that this new car is a messy pig to get to the oil filter on is further incentive. I think the trend here IS to go longer OCI. Much longer, and, on Dino. I've been chided many times that syn is a waste of money even at 7500 mile OCI.
Out in the greater world, however, the old ways are still being perpetuated. NO ONE in the oil change industry from the dealer, the oil companies, filter-folks, parts stores, Jiffy-Lube, and all the rest is EVER going to suggest or push a "radical" new theory of a basic car-care tenent such as longer OCI when their business could instantly, or nearly so, be cut by two thirds. In fact, I think they'd do everything they could to squelch the idea of long OCI at every level of advertising there is.
Longer OCI is a very well-kept secret, and it will continue to be so for a long time. Folks who would like to look for conspiracies in the oil industry regarding gasoline prices would be better served looking for a far wider "conspiracy" (if not as intrinsically critical to the economy) involving all of the many elements of the oil change industry. These folks after all, are deliberately (if understandably) keeping people in the dark regarding longer OCI. Which of course, is getting them into the parts store, garage, and quick change shops at least two or three times a year more than is necessary. In a new age of short oil supplies and concern for the environment, one would think folks in the know would speak up, wouldn't one?

I occasionally run synthetic in my wife's Expedition. I always say I'm going to run it for 5k. What usually happens is it takes my wife FOREVER to go 5k miles, so I wind up changing it after 3k miles, or approx every 4 months. It gives me something to do in the man-cave. Actually, I'm glad she doesn't put many miles on the Expedition; it helps to keep the fuel bill low-ish.quote:

I know that Quaker State has the same 3k mile/3 month recommendation on their website. I'm sure there are others.....quote:
