Changing just the oil filter?







this thread. Move it to OT please nah OT would kill him
AMSOIL recommends changing filters at more frequent intervals than changing their oil - considers it a waste of money to change both at mfg suggested intervals.
http://www.go-synthetic.com/oil_change/oil_change.htm
"AMSOIL Synthetic Motor Oil, in gas aspirated engines, is RECOMMENDED to run for 25,000 miles or one year (5W-30, 10W-30, 10W-40) in a mechanically sound engine, providing of course, the oil is kept free of contaminants by changing the oil filter according to the manufacturer's recommendation or, when using an AMSOIL Oil Filter, changing the filter at six months or 12,500 miles which ever comes first. "
Question:
"Why does AMSOIL say to change the AMSOIL SDF Oil Filter at six months regardless of the mileage."
Answer:
"Once an engine is run with new oil, byproducts of combustion are introduced into the oil. These byproducts are harmful chemicals that continue to degrade the integrity of the motor oil as well as the oil filter media even though the engine may be off. This is why a time limit is published as well as mileage. Short trip driving can be just as detrimental to motor oil and filters as high mileage use, and even more so in some cases. It’s possible that the oil is still intact at the end of the published time limit..."

I mean really...when it gets down to it would you do what AMSOIL says? If you do and for some reason it doesn't work out for you who is left holding the bill?? Personally I don't doubt they did all the research etc. and what they say is true..just not willing to try it myself. Of course I am not gonna change the filter half way thru either
but thats just me being an azz
But I also wouldn't belilttle someone repeatedly over what they consider a serious question, and which is supported by a company that many on this forum consider a leader in the industry.
And as for them not doing their research...
"Amsoil coined the phrase "extended drain interval" and it's been validated by almost 30 years of industry testing and by hundreds of thousands of motorists and millions of over-the-road miles."

While really not meaning to stir the pot, I do think you guys... and gal are being a little hard on the original poster. I thought he had a legitimate question.
FWIW, here is the exact AMSOIL Product Change Interval Guide.

WOW removing that drain plug while your lying under the car is soooooo much extra work!!






reading is fundamental.....I said I didn't doubt them I just wouldn't do it in my car....
once again you prove my point.......you argue with every reply.
why not just give up and realize that everyone here just doesn't agree with you?
What is the difference between Mobil 1® Extended Performance and the currently available Mobil 1?
If Mobil 1 Extended Performance is recommended for 15,000-mile intervals, what’s the maximum limit to which it can be pushed? In other words, if a driver goes an extra 1,000 miles or so, is he going to damage his engine?
Does the Mobil 1 Extended Performance meet GF-4 specifications? How did the new specification impact the development of the high-endurance product line?
Do I need to flush my engine before switching to Mobil 1 Extended Performance?
Upon what driving conditions are these performance claims based? Normal or severe driving conditions?
If I go longer between oil change intervals, do I need to change my oil filter more frequently? Or do I need a special filter?
To achieve the best peace of mind related to engine protection, many vehicle owners change their engine oils every 3,000 to 4,000 miles. Is this practice rendered meaningless with the advent of the Mobil high-endurance oils?

What is the difference between Mobil 1® Extended Performance and the currently available Mobil 1?
Mobil 1 Extended Performance formulas are designed specifically for today's longer service intervals and are guaranteed to protect for up to 15,000 miles or one year.
Mobil 1 Extended Performance has a unique formulation with boosted level of protection and performance. These formulations with the Advanced SuperSyn System contain 50 percent more SuperSyn, 36 percent more anti-wear additives, and 37 percent more cleaning agents than the current Mobil 1.

Mobil 1 Extended Performance is recommended for up to 15,000-mile or one-year oil change intervals. However, if your vehicle manufacturer recommends an oil change interval beyond 15,000 miles and Mobil 1 meets the performance level specified, you can be assured that Mobil 1 will go the distance.

Does the Mobil 1 Extended Performance meet GF-4 specifications? How did the new specification impact the development of the high-endurance product line?
Mobil 1 Extended Performance contains extra performance additives to deliver exceptional performance and protection. This fully synthetic technology is designed specifically for longer service intervals. While it does not meet all the requirements for GF-4, it provides protection of the critical engine parts well beyond conventional engine oils including conventional GF-4 engine oils, and meets all the engine durability and protection requirements for GF-4. Additionally, Mobil 1 Extended Performance oils exceed the requirements of API SL/CF and various ACEA (European) specifications.

Do I need to flush my engine before switching to Mobil 1 Extended Performance?
You do not need to flush your engine prior to changing to Mobil 1 Extended Performance.

Upon what driving conditions are these performance claims based? Normal or severe driving conditions?
These claims relate to all typical consumer driving conditions, excluding those mentioned below. In other words, if you drive under normal conditions and use Mobil 1 Extended Performance in your vehicle, the oil is guaranteed to protect your engine for 15,000 miles. We also recommend that drivers consult their owner’s manual while their vehicle is under warranty, and follow the guidelines set forth there. Additionally, we recommend that if consumers drive routinely in severe conditions that they follow the oil change interval recommended in their owner's manual for severe conditions. We define "severe conditions" as:
racing or commercial applications;
frequent towing or hauling;
extremely dusty or dirty conditions; or
excessive idling.

If I go longer between oil change intervals, do I need to change my oil filter more frequently? Or do I need a special filter?
Continue to change your oil filter when you change your engine oil. Special filters, or more frequent oil filter changes are not required.
However, Mobil 1 Oil Filters provide outstanding performance during longer oil change intervals. Mobil 1 Oil Filters are designed to offer excellent efficiency (remove more engine oil impurities) and high capacity (60 percent greater capacity than conventional oil filters), which make them ideal candidates for longer oil change intervals.

No, consumers should continue their current maintenance practices. They can now achieve peace of mind knowing the guaranteed performance and protection intervals of the new Mobil line of high-endurance oils. Mobil Clean 5000, Mobil Clean 7500, and Mobil 1 Extended Performance protect critical engine parts from lubricant-related failure for 5,000/7,500/15,000 miles - guaranteed.

What's the difference between Mobil 1 and Mobil 1 Extended Performance?
Mobil 1 with SuperSyn technology exceeds the latest industry and OEM requirements. It is designed for vehicles under warranty and will provide protection for the maximum oil change interval recommended in your owner's manual or by your oil life sensor. Mobil 1 is designed for excellent low temperature and high temperature operation. It is designed to provide the maximum drain interval as recommended in your owner's manual. Mobil 1 Extended Performance is guaranteed to protect your engine for 15,000 miles or one year, whichever comes first.

When I worked at autozone in 93-96 Mobil 1's literature said you could go 12 months/12K miles. Then they dropped that and said to go with what your manufacture states. Now they are back to their own mileage policy again. I think it has something to do with the politics of so many different manufactures starting to use them in the 90s. They didn't want to contradict the owners Manuels.

Yeah I can see the conflict between oil companies and auto makers. You and I both know that if a customer has an issue its gonna come down to what the manufacturer says in the manual for warranty issues etc. Alot of the new cars have 7500 listed in the owners manual which I think goes back to what you stated about the filters being more capable to go the distance which kinda supports the arguement of why change it half way thru.





You asked a question and asked for opinions.
Funny once others gave you their opinions you became defensive. Then you decide your only defense is to insult others who have a different opinion.
It turns out you did not want opinions after all, why did you ask for them then?
BTW I am a "lady"
