Do any of you guys use synthetic oil in your vehicles ?

There have been a couple of extensive threads on this subject in the past.

Try a search for them.

Yes. Save yourself some time and go buy some Mobil 1. I change the filter at 3,500 and the oil and filter after another 3500. Running it for 7k makes it pretty affordable compared to the dino-juice!!

Yes, that is all I run, along with the xtra guard or high mileage filters. Never a problem and its cheaper than changing oil at 3-4K.

There are some topics you never get to the bottom:
Astronomy
Mathematics
Music
oil for your car

I am still arguing about oil for my lathe headstock.

There is a website, Bob is your oil guy where you could read for a long time.

What chainsaw should I buy ?

I use synthetic Rotella in my pickup and bought some extra fancy synthetic Amsoil for the 4-wheeler.


No reason why it shouldn't work(especially in cold weather).

5 quart jug of Mobile 1 is $25 at Wal-Mart, To cheap to not use.

Mobil 1 extended mileage with a Napa Platinum filter, change it out every 12-15K miles. Seems to work just fine.

I use it now so I don't have to change my valve cover gaskets quite so often.

LOL

Disconnect your speedometer cable and you have to change them even less, because you aren't putting that many miles on your vehicle...

Can I just cover it with elec tape like my CEL?

Here's the Link you really need. All questions are answered several times over.

I use full synthetic in newer gas engines, the top choices for me are AmsOil, Royal Purple, Schaffers. Schaffers came out ahead of Royal Purple in the last test I saw. Rotella in the Diesel, Valvoline or Castrol GTX in older stuff.

Mobil 1 is recommended for my corvette, so that's what I use.
I use a blend in my truck.

I'll have to catalog that idea....

THAT IS AN EXCELLENT IDEA!

YOU really KNOW YOUR STUFF!!

That's what I use in my Tacoma with 135,000 on it.

I can't bring myself to go 7,000 no matter what they say so I still change at 3,000.
I only put about 5,000 a year on though so the added expense isn't a big deal.

I've been using Mobil 1 since 1974 or '75. Never had a lubrication or wear problem, even after 275,000 miles. One car exceeded 275,000 miles and the compression was still within spec for a new car! It does cost more, but I feel it's worth it.

Napa filters are great! I use MotorCraft in my Ford 6.0 Diesel but use Napa Gold filters in my wife's vehicle and got the bulk box of 12 on sale for ~$3.25/ea!!

I changed to Mobil 1 after the first 3K on my Tacoma and its had nothing else since 2002. Changed every 5-6k, 230,000 miles later still running strong.

And I run mine MUCH harder than you could ever imagine!

Mobil 1 oil and Mobil 1 filter, 272,000+ miles so far.....

That's what I've got but the wife complains that it's to heavy.....

Penzoil Platinum or Mobil 1 is about the best you can get for the money. I typically run Purolator, Wix(Napa Gold) pr Motorcraft filters. I change oil and filter around 5k

For those of you with mega-miles on your vehicle and regular oil changes have been performed, do you actually think it is becaused of the brand of oil used or the regular intervals of change?

My 2012 tundra came with synthetic oil.. Cheaper to drive with longer oil change times.. Still I change at less than 10,000 miles..

Yep, no other way to go....

I use Castrol Edge, formerly known as Syntech.

I use to work with a fellow that would only change his filter every 5000 miles and add a quart of oil. He never kept a car past 200,000 miles so I can't tell you how that worked out in the looong run, but he never had any oil related trouble while he owned it.

Good question.

I picked up an old (2003) Land Rover with 120,000 on it and so the high numbers others are quoting give mo hope that I can hang onto it for a while.

Clear coat is shot and headlight covers need to be renewed, but the other issues (old seat vinyl, worn steering wheel, etc.) seem manageable and it has plenty of power. I definitely will try synthetic –– even if the valve cover gaskets leak, as they seem to be doing.

The intervals here, have never been exact, but have tried to be.

The most miles is an explorer, 96, that has something over 350K miles on it now, ODO does not work, I have to guess at miles to change... synthetic since the first change...

Its been going that way in the ohter vehicles so far too...

People who claim to know have told me that the filter is the weak link in the system and that if they were more sophisticated, you could leave any kind of oil in forever, so that would make sense, not that I would do it.

I don't believe that ANY kind of oil could be indefinite, but its always the filter that clogs, just like any filter, that allows particals not to be stopped but to circulate and wear, at least from what I've researched a bit about em.

I work in an industrial environment and have oil dist. reps in and out. They charge for oil samples but I asked him about automotive oil and he showed me how he's sent in samples from his company rig. He ran the oil for 25k, sampling every 2500 or 5k and he said even at 25k it still had enough additives and was clean enough to keep going a little longer. He changed it, but he said he goes 15k to 20k on his personal rig now.

Dino-oil, Wix filter every 5 - 6 k with no issues.

The reason I do synthetic with a high quality filter and long interval between oil changes is mainly the convenience of not having to take the vehicle in for oil changes all the time. We drive a lot.

Filter only, Ed? No fresh dino juice other than to top off?

Yes - all of 'em..
