honestly.walmart synthetic vs. mobile 1

[spaceman]

assuming you change your oil every 2500 to 3k.

 

[spaceman]

for those who may not know, wally world synth is around $12 for 5 qts, mobile 1 around $23(here in ma leastaways)

 

[Turin39789]

if you change your oil every 2.5 - 3k why not just use dino?

 

[kingtas]

All I know is that my cars didn't leak oil until I put synthetic in them.

Where did you hear that? What does the car do, stop and open a special valve to dump the bad oil out?

If you're changing your oil that frequently, I would think not. You could always to a used oil analysis to see what's going on in there.

How often does the subaru manual tell you to change the oil?

3k iirc.

 

[Turin39789]

what year/model/engine type?

 

[spaceman]

04/wrx/2.0l

 

[ViviTheMage]

weird, i think i do 5000 miles , or was it 6000 on synthetic in my jetta 1.8T

comes out pretty damn clean even after 6k miles.

cleaner then non-syn at 3k miles.

 

[d3n]

I have both my cars using Mobile 1 Synthetic. I buy it from Wally World too. I go a little longer than the recommened change schedule at times. With Synthetic thats every 7000 miles. Sometimes its 10 -11k before I can get the wife out of the van for a bit to change it. With Mobil 1 I don't really worry about it.

If a car has some milage on it and it's only had regular oil, putting synthetis in it will cause leaks more often than not. This is because there is slightly more wear with regular oil, but oil residue builds up and prevents leaks. When you switch to synthetic, it ends up removing the build up and whiel you get superior lubrication, you will also likely notice some minor oil leaks.

As for the difference, yes there is. Most "synthetic" motor oils are not a true synthetic. True sunthetic is completely made in a lab and PAO based, but some have removed the PAO (which is the synthetic part and which makes up about 70% volume) and replacing it with a "hydroisomerized" petroleum base stock. PAO base stock oil is more expensive to create, but it (arguably at least) offers superior lubrication.

Now the main reason for using synthetic is the idea of changing your oil less often. If you still plan to change at 3 months/3000 miles, then there is no need to use synthetic. Even the less expensive synthetics should be plenty capable of protecting for 6 months/6000 miles minimum.

Some brands such as Royla Purple, Amsoil, and Mobile 1 (all use PAO base stock) sell oils that claim to last longer than 6 months (up to as much as 25,000 miles), but you still need to change the filter every 6000 miles or so.

 

[waggy]

I thought part of the reason to use synthetic was you would not have to change at 3k miles. you could stretch it out to 5k+ without fear of damaging the vehicle?

You were told incorrectly. With those intervals, you would be just fine with a quality dino oil. And you should stay away from Mobil 1 with an EJ205. Lots of reports of early bearing failures from people who had used strictly Mobil 1, while no such reports from people who had used other oil brands. Personally, I stick with Valvoline SynPower 10W-30 and change every 4k miles in my stage 4 bugeye.

edit: owners manual recommends 7.5k mile oil change intervals under regular usage. Note all the service intervals are in multiples of 7.5k, i.e. 15k, 30k, 60k, etc.

really isn't much of a difference between the cheapest brand X dino oil and a highend synthetic.

That isn't a problem with the oil.

Synthetics are usually more resistant to sludge build up etc. They also do not mix perfectly with conventional oil. Sure the two will dillute each other, but it isn't perfect.

Your car leaking oil means there is a problem with your seals somewhere, and the oil is getting through it. Those seals may have been sludged up before you ever added synthetic.

It is and it isn't... odds are that they probably would have continued to not leak if he'd kept using dino oil. I've always heard that it's generally a bad idea to switch to synthetic if your motor has a lot of miles on it for precisely this reason.

Myths about Oil Changes

Amsoil(Learn it, Live by it. Unless you trade your vehicle in all the time, and do not care about how long your engine will last)

Several car manufacturers are recommending 6 month/5k miles. With 3 month/3k miles for severe driving conditions.

So ask yourself how do you drive, and whether you are in stop and go traffic all the time, or long trips.

If you search on Google for oil stress testing, you can find charts that rate at what temperatures the oil breaks down, etc.

Hands down Amsoil is considered the best of the best.
Plus Amsoil, with Amsoil filter is 1 year/25k miles, or 1 year 15000 mile under severe conditions.

I edited my response because I had a bit of false information.

You are right, in a sense. If your car has a 100k miles and is running a little rough, but doesn't leak oil, putting synthetic in it isn't going to do you any good. It is sort of like painting a rotten board. The board is still rotten beneath the paint. The paint is going to just fall off with pieces of the wood. If the wood is brand new, the paint is going to protect it, and better paint will protect it more. But good paint over old paint that let the board rot a bit isn't going slow the rot.

Same thing, if your auto transmission is having problems a flush may kill it, but it wont hurt a brand new transmission.

It's trying to do to much to late.

Do people honestly beleieve that Walmart has it's own refinery and puts out a cheaper sort of oil to sell in it's stores ?
Walmart gets it's oil from one of the major refineries and it is just labled for them. It's probably the same oil you're paying premium prices for in a service station. My sister and BIL both worked at a BP refinery and when Texaco ran out of super, who do you think they called? There is no such thing as cheap gas or oil it's all refined to the same specs it is just the point of sale that makes the difference.
