use of motor oil when the car is older

[sb2463]

Hello Is it ok to go away from 5-25 blended when the car is older and approaching 100,000

[Gerry24]

I use 5-20 high mileage blended... I'm @ 157,xxx

[sb2463]

What about using non Blended oil? I have always used the Blended, however I am out of the country with the car. Hard to get the blended except at a dealer.

[Gerry24]

The conventional oil shouldn't be a problem, unless you were consistenty using synthetic...

[fastblackmerc]

Doesn't matter if your using full synthetic, synthetic blend or straight dino.

I'm running 0w30 Mobile One full synthetic.

[xopher]

straight dino.

Haha this is great :up:

[Marauderjack]

I had 256,172 miles on my OEM motor (last 172K Supercharged) when it blew......Mobil I it's entire life and it never used oil!!:D

The block only needed honing for the rebuild....crankshaft only polished!!:eek:

These new motors will last indefinitely with routine maintenance as long as oil meets specs set forth!!:beer:

BTW, mine blew due to bad gas....we think??:confused:

[ctrlraven]

At around 135k miles I switched from Mobil 1 5w20 to 5w30HM, at 235k (I think) now and still going but it does have it's issues as any high mileage motor could have (rings are worn which allows more blow by and some seals are weeping) but I don't ever need to add more than 3/4 of a quart over a 5k mile oil change interval.

[james79stang]

I am @ 260k and still using 5-20 motocraft blend, not thinking on changing anytime soon.

Why use blended when full synthetic is about the same price?

[fastblackmerc]

Why use blended when full synthetic is about the same price?

What planet are you living on??

It's not the same price.

Motorcraft 5w/20 synthetic blend - $5.89

Mobile 1 5w/20 full synthetic - $9.79

Castrol 5w/20 dino oil - $5.99

Valvoline dino oil - $3.99

Prices (per quart) are from the Autozone webste for the store closest to where I live.

[NXSBOB]

6 quarts Mobil 1 full synthetic at Costco when NOT on sale is $36, that is $6 a quart.
When it is on sale, it is only $28, that is $4.6 a quart.
5 quart container at Walmart is less than $24. That is less than less than $5 a quart.

The planet earth. Where are you?

[fastblackmerc]

From your same website....
Mobile 1 (full synthetic) 5w20 - $23.88 for 5 quarts = $4.77 / quart
Motorcraft (semi synthetic) 5w/20 - $17.97 for 5 quarts = $3.59 / quart
That's a $1.18 difference.

Yes and a lot cheaper than the "Mobile 1 5w/20 full synthetic - $9.79" and "Motorcraft 5w/20 synthetic blend - $5.89" you posted.

MOTORCRAFT 5W-30 synthetic blend...:bandit:

[JOEMERC]

Walmart prices are the best for oil ,I get Pennzoil 5w30 5 quart jug for $25 its $10 more at Advance Auto,the way I look at it our cars are worth it to use the full synthetic oil ,we even pay more at the pump cause our cars use premium gas so we'll might as well use a premium oil my .02.

[JOEMERC]

Forgot to mention that's for Pennzoil Platinum full synthetic oil for $25 :)

Hello Is it ok to go away from 5-25 blended when the car is older and approaching 100,000

According to your vehicle’s owner’s manual, your 2003 Mercury Marauder requires a 5W-20 motor oil. Given that you mentioned the vehicle is reaching 100,000 miles, we would recommend moving to a high mileage motor oil. Specifically, we would recommend Pennzoil Platinum High Mileage 5W-20. Pennzoil Platinum High Mileage is the first of its kind full synthetic high mileage motor oil made from natural gas. It is designed to deliver less oil burn off than other high mileage oils, as well as help to reduce leaks and oil consumption. Hope this helps! - The Pennzoil Team

I buy approximately $500.00 of oil from Walmart everyday...I'm here to tell you Walmart is the best for Mobil 1 oil.
Full synthetic comes out to about $4.77 a qt.


Same price for High Mileage Mobil1

High mileage is the same oil except it has a seal sweller added to it.

If you don't have any leaks why use high mileage oil?

[Mike M]

No leaks- no need for seal swellers but the thought process is cars with over 75k sometimes start to wick out a bit, not so much a leak but the just enough to make it a bit wet. The seal swellers or expanders can help stop this.

Don't you have a wholesale oil distributor in your area? Yes they are not much cheaper than WallMart at the minimum purchase level but at that kind of volume you should qualify for discounts and free delivery.


If you don't have any leaks why use high mileage oil?

Because you want your engine to leak oil? :dunno: Fact is those additives soften the seals just like the various stop leak additives for engine, transmission, and power steering oils. That means that while they may stop or slow down a leak in the short term in some cases they also accelerate the wear of the seals in the system that were not leaking. So stop/slow down one leak for awhile and then have a whole bunch more pop up down the road.

I'll stick with regular non-high mileage style motor oils because Ford like most automakers recommends using no additives in the oils used in the car even if they are added with the oil before you buy it.

I got rid of my bulk tanks a few years ago and I got rid of my wholeseller. They could not come close to Walmart prices. Also I don't have to sit on 600+ gallons of oil with all that money tied up. The Walmart is across the street from my shop so I use the "just in time" inventory process just like all the automakers switched over to in the 90's.

Oil changes only account for about 7% of my total gross, we specialize in everything from eurpean repair, engines, transmissions etc. Also tint, car wash and full detail.

According to your vehicle’s owner’s manual, your 2003 Mercury Marauder requires a 5W-20 motor oil.For the sake of complete accuracy, the owner's manual does not use the word "requires". It says that 5W-20 is recommended.

Gotta love these oil threads! All several 100 of them!

Sounds like your wholesaler was sticking it to you. The one we used when I was still in the business was pretty close to the same price as Sam's Club on the min purchase and would beat them if you bought a larger amount. Bulk was significantly cheaper. As far as sitting on the money the wholesaler offered 2-10 net 30 on their invoicing so either a little lower net price or sell it before you pay for it.

But if it works for you that's great.

[Mike M]

Trust me...going to Walmart and buying 5 qt. jugs is the most cost saving efficient way of doing it.
I did it the old way for decades (bulk).

I'm pretty sure I am our local Walmarts biggest customer.

I bet you are their biggest customer overall with that kind of daily purchasing. Again whatever works best for you. The obviously have to consider your motor oil purchasing patterns when making their orders because around here many of the WalMarts do no stock enough of a some brands in a specific wt to do one oil change unless you've got a car that takes only 3qts.

[Marauderjack]

Why change anything at 100K miles??:confused:

My engine had 256K miles on it when the bad gas (?) incident took place......block only needed honing and crank polishing......virtually no wear and no leaks with Mobil I 5W30 all it's life!!:bows::beer:

This is confusing. What about filters? Is there a better one? :confused::confused:
