Post subject:  What oil do you use?
I'm about 1000 miles away from my first oil change since I got my 04 Rennie.

I was looking today at some cases of oil, but what do you all use? Here's what I was looking at:

Mobil-1 Synthetic, 6qts, $29.99
Castrol Synthetic, 6qts, $22.69

Any recommendations?

Also, do you still keep up the 3000 miles per change with synthetic, or do you go up to 7500 miles as many recommend now?

I use Amsoil 5W-30 and I am on a 15,000 mile or yearly change interval. I do rarely put 15,000 miles on a vehicle in a year though. The Amsoil ASL 5W-30 and Ea series filter are guaranteed for a year or 25,000 miles.

Here is some Amsoil Vs. Mobil 1 reading.
http://www.lostjeeps.com/forum/phpBB3/vie ... php?t=8193

So lets say it costs about $48 (w/ tax & not counting driving to get it all) for a Mobil 1 Oil & filter change and you could get double (or more) the miles out of Amsoil FULL synthetic oil & Amsoil filter which are both Better for about $16 more would you do it?

If not, Why not?

You would save time doing fewer oil changes a year, less waste oil to dispose of, better for the environment, better oil and filter = better for your engine, oh and shipped to your door in a few business days instead of having to go hunt it all down at Wally world and whatever Napa or Carquest has the Wix or Mobnil 1 filter.

STOP USING MOBIL ONE!!! they changed it, its no longer all synthetic, so you are wasting your money.

i have used nothing but mobil 1 since the breakin oil change, but they recently changed the base on many of their grades to mostly conventional .

DO NOT use the extended performance ones, they are the most notable culprits.

i will be using only amsoil products from now on

You have to read the label...Mobil one started marketing a blend of syn and dino to be cheaper and sell easier at places like Wallyworld.

last change, i used quaker state, 10/30, and a fram filter!!!
this was before reading you guys opinion on fram, tho i'm still not convinced they're so bad. after all i've used them for ever.
tho i may have noticed a small decrease in mpg's.

I usually use Quaker State synthetic blend 10W/30, but I have also used Mobile Extended Life. I like both brands, though Mobile is really considered top notch. As far as oil filters goes I personally never saw the reason to spend ~3x as much money on the Mobile 1 filter. I found this http://minimopar.knizefamily.net/oilfilterstudy.html a while ago as well. I also never use Fram products, IMO they're garbage. I tend to use Purolator Pure One and really like them.

I have been using Mobil 1 5w30 and it says "fully synthetic" on the label. It is the regular one - not the extended performance one.

I don't think Mobil (or any reputable name brand co) would put "fully synthetic" on the label and fill the bottle with dino or a blend. Too many people out there have their oil tested and someone would find out and blow the whistle and their reputation would be severely damaged, they would lose sales, and be in some "hot water" with the government over labeling laws, etc.

In my opinion, I wouldn't use a blend. Either go full syn or dino. I believe the blends are just a marketing gimmick (sp?) and they don't say how much synthetic is in there at least on the bottles I read.

Article from 2005....
"ExxonMobil Follows AMSOIL into Extended Drain Market

Motor oil technology has gradually progressed since the days of the earliest automobiles. In those days, standard motor oil drain intervals were between 500 and 1000 miles, and motorists had to switch viscosity grades with the changing of the seasons. The development of oil filtration and additive technology in the 1930s allowed drain intervals to increase to 2000 and later 3000 miles, while the development of viscosity modifiers in the 1940s allowed the formulation of multi-grade oils that could be used in both hot and cold temperatures.

According to AMSOIL Vice President Alan Amatuzio, the introduction of ExxonMobil extended drain oil is long overdue. "While AMSOIL INC. has certainly proven that extended drain intervals provide valuable benefits," said Amatuzio, "the fact that ExxonMobil is finally saying the same thing brings the message to even more people. ExxonMobil's move is significant in that more consumers will now recognize AMSOIL as the pioneer in extended drain oils and will benefit from the advanced technology we introduced 33 years ago."

ExxonMobil recently announced a new line of motor oils recommended for extended drain intervals.
It was only a matter of time before another company followed the path forged by AMSOIL over 30 years ago. Some motorists may recall that Mobil also followed AMSOIL into the synthetic motor oil business, introducing its synthetic motor oil several years after AMSOIL. The technology for extended oil drains is obviously available, but until now, the major oil companies have had other agendas. Marc Graham, who is president of Pennzoil-Quaker State-owned Jiffy Lube International, was quoted in a 2001 Lubricants World interview as saying, “At [PQS] we use a number internally that if we [shortened the drain interval] by 100 miles [for each car serviced], it would mean an additional $20 million in revenue for the company.” He also explained that “if we could move our customers to get one more oil change per year, it’s worth $294 million for the oil change alone and $441 million in revenue, when you include the ancillary products and services customers typically buy along with the oil change.”

Mobil backed off 25,000 mile oil change intervals in 1974.
Mobil briefly recommended 25,000 mile oil drains in the 1970’s. It’s not difficult to figure out who they were trying to compete with. AMSOIL was the only other company offering synthetic motor oils and recommended 25,000 mile drain intervals. However, it may be that because vehicle manufacturers weren’t yet comfortable with extended drain intervals, Mobil retracted its extended drain recommendations and simply recommended motorists follow the intervals specified in their vehicle’s owners manual. Of course, traditional oil change recommendations also allow Mobil and other motor oil companies to sell a lot more oil. Everyone wins but the customer.

AMSOIL stands apart from the competition.
AMSOIL has always formulated its products to be the absolute best, continually researching ways to make its already outstanding products even better. Other oil companies, however, are beholden to shareholders, and one could speculate that their incentive is to maximize profit. They formulate oils down to a price, rather than formulating them to be the best they can be. Then, they price their products to maximize profits. In addition, AMSOIL has 33 years of experience blending premium extended drain synthetic oils. That’s 33 years worth of proven performance in the field.

A close look at ExxonMobil’s new long drain motor oil line reveals that two are petroleum based, one is a synthetic blend and only one, Mobil 1 Extended Performance, is a full synthetic. The petroleum based products are recommended for 5000 mile drains, the synthetic blend for 7500 mile drains and Extended Performance for 15,000 mile drains. However, a look at the fine print reveals that ExxonMobil is still recommending drivers follow the oil drain recommendations listed in their owners manuals during the warranty period. AMSOIL synthetic motor oils are recommended for 25,000 mile or one year drain intervals in both new and older vehicles. The AMSOIL warranty stands behind this recommendation.

AMSOIL has recommended 25,000 mile/one year drain intervals since 1972.AMSOIL delivers the highest quality lubricants on the market. It’s the AMSOIL identity, and it’s what customers expect. Al Amatuzio coined the phrase “extended drain interval,” and from the beginning, AMSOIL synthetic motor oils have been formulated for extended drain intervals.

Vehicle manufacturers are pushing for extended oil drain intervals.
Vehicle manufacturers in Europe have been recommending extended oil drains for years. In fact, the average drain interval in Europe is 10,000 miles. Vehicle manufacturers in the United States are definitely coming around to extended oil drains as well. Most owners manuals from recent model vehicles recommend 5000 to 7500 mile oil drain intervals. In addition, oil life monitors have become increasingly common on today’s vehicles, allowing and encouraging motorists to increase drain intervals up to 12,000 miles, even when using conventional oil. Vehicles equipped with an oil life monitor no longer recommend oil changes based solely on mileage. The system measures engine operational data such as temperature, revolutions and speed to determine when the oil is nearing the end of its life.

The motor oil industry is faced with the extended oil drain interval issue.
The success of oil life monitors has posed a threat to motor oil companies who insist oil must be changed every 3000 miles. It becomes increasingly difficult to maintain this position when vehicle manufacturers are recommending significantly longer intervals with the use of their oil monitoring systems. This is no doubt one of the reasons ExxonMobil finally introduced a line of long drain motor oils.

AMSOIL products are available for less.
The suggested retail price of the top oil in ExxonMobil’s new line, Mobil 1 Extended Performance, is $5.79 to $5.99 a quart. That’s right in line with AMSOIL 5W-30 and 10W-30, which retail for $5.95 a quart. By registering as an AMSOIL Preferred Customer, customers pay only $4.85 a quart, and even less when purchasing by the case."
Note: Pricing has changed slightly since this article.

PLMK if you have any other questions on Amsoil products.

BTW, The whole advertising a hydrocracked or blended synthetic as full synthetic issue stems from a lawsuit Mobil 1 filed against Castrol where Castrol won the right to call their non-Full synthetic "Syntec" a Synthetic. Other compaines, realizing they too could do that, reformulated and followed suit. Who can you trust these days?
