I'm about to install synthetic

[mossad]

I have my 5qt jub of M1 synthetic....the big #1 is starring me in the face at this moment.
But I keep reading posts about ARX this and ARX that. The vehicle in question has only 67k, and some slight seal swell/seapage, but dry overall, no drips on the ground at all.

Mobil tells me I can just start using it, but stick with a short OCI of around 2-2500 for the first one. Should not have any problems even if I don't do an ARX treatment first right?

Also, I'm sticking to a short OCI of 3-4k, so if any one of you wants to talk me out of using synthetic, I'll listen. I can still return it.
Walmart even takes used oil back..LOL But I would never do that.

The only reason I would ARX your 67k car is to clean up the ring pack and look for more power.
Same reason I use techron in cars with those miles. Otherwise dump it in.

Your next post if the oil turns black overnight will tell me whether you are benefitting from switching to M1 or could have used an ARX. But it's no sleep killer - you can still ARX with your short OCI later with just a dino clean phase.

 

[m2200b]

sorry for ARX I meant dino rinse phase.

But this is what Mobil's web site says about this issue...

Question:
Switching to Synthetic Oil in Higher Mileage Vehicles
Does switching from a petroleum-based oil to a fully synthetic oil on a higher mileage vehicle (75,000 miles) have any harmful effects? I've heard that the synthetic oil, because it is cleaner, may actually loosen some of the build-up from petroleum oil and has the potential of clogging the pump. Is this true or does one simply need to change the filter more frequently for the first few thousand miles after switching? Thanks

Answer:
When switching to Mobil 1 in higher mileage vehicles, we recommend an initial short (2,000 to 3,000 miles) oil change, both oil and filter. This will allow Mobil 1 to clean some of the engine deposits that have accumulated over time. Following this initial short oil change, continue with your normal oil change interval.

if you are going to spend 5-6$$ a quart...why not leave it in 5-7K at least?? heck..at that point do a UOA to see if you can goo further...will also let you "know" whether you can go that far and futher with your next Mobile ! change out...other wise just find some Havoline or Chevron for 2$$ a quart and dump that too soon too...at least then you aren't wasting $$ just good oil

 

[mossad]

I don't care what any of you think...any engine can benefit from a synthetic, EVEN if you chose to use a short OCI.

 

[mossad]

Ok, I admit it, I was getting frustrated...
Let me restate... Even with a short OCI, won't synthetic protect better than a conventional, even if you chose to do short oci's?

 

[ScottB]

Of course it will.
Use it.
Be happy.

There is a open mind...

Yeah, spend $4-$7 a quart for short OCI.

Smart move!

Some benefit..

Maybe for the oil companies...

But you don't care what anyone thinks so we will leave it alone.

But in case you want to listen, with a 4-5k OCI, unless your manual states you MUST use Syn, just run a good dino and use the extra cash for something else, Like gas...

With that short of OCI, ANY oil is going to protect. Your engine is not going to know the difference.

Take care, Bill

I guess it depends on what you mean by protect better. I haven't seen any evidence that wear numbers are better with synthetic vs a dino. But in terms of shear stability, high/low temperatures, and extreme conditions, synthetic has the upper hand.

Bill, you lyin about that 250K on your Jetta with dino and no issues, consumption, or ANYTHING!

You bet.. (it has over 290k now!)

I drove in the end of June (it's now in San Diego as my Sister in Law owns it) after changing the fluid in Transaxle for the first time

(should have changed it sooner) and it ran fine. It uses about 1/8th of a inch in 4k miles on the dipstick.

The everything is still orginal on it. The Timing belt has been done quite a few times and CV boots don't seem to last to long (they crack quite a bit) (it's had maybe 10 of them on since new) but its still good!

I did tell her to look into new struts as I'm feeling that they need to be replaced. The car does dip and bounces back quite quickly and they need to be looked at.

There are times I wish we kept it (we bought a Accord and wife wanted to "help" out little sister) as if I still drove it, It would have over 400k on it now.

My Corolla will be kept and it's not even 2 years old yet and passed 55k miles.

So I'll just keep it going to show what I've been doing for years still works!

No joke.. Sorry.

Take care, bill

PS: One thing though on the Jetta which is sad.. We replaced the Windshield about 7 years ago and some clown came out in a truck and TORE out the old one and put in a new one. He scratched the frame and now there is TONS of rust all over around the Windshield. Since its a white car, It's ugly. Sad..

Just use the synthetic with confidence that when you approach 5000 miles, there really will be no need to change your oil. Maybe at 10K you can plan the oil change, but still not be in a rush. If you had dino in there all that time......well, enough said.

For the first "long" OCI 5K will be fine.

 

[mossad]

Ok, but I've spoken to dozens of people who even change their own synthetic every 3000 miles.
If money is no object, it just seems to me based on the characteristics of synthetic that your engine will be more prortected vs using a conventional.

Ok, If money is no object.. I'll PM you my address and please make sure you spell my name correct on the checks you send me...

Oh, and if you change your oil every 3000 miles, 2000 miles or 1000 miles with Conventional, Blends or Syn your engine is protected the same.

Syn is used for longer OCIs or if the engine REQUIRES it. (the manual states it or your force feeding it. (turbo, etc).

Your dozens of people are caught up in the marketing of oils. They are not getting "more" protection IMO.

They are throwing $$ down the crankcase drain...

Go for it. It's your $$ and engine. It will not HURT it if you use Syn and change it every 3000 miles at least.

It's just not "better" for it.

Take care, Bill

I would like to see some statistics on people who change synthetic oil at 3,000 miles.

1. What percentage are in a financial position that money is truely not an object.

2. What percentage aren't in that position, partially because they **** away their money needlessly.

 

[sxg6]

I use to change synthetic every 3000 miles too, but then i found BITOG and learned i was throwing my money away. I now change my synthetic every 7,500mi, and my engine runs just fine, with zero signs of sludge.

The idea of a 3000 mile OCI is marketing hype only if you're using a synthetic. Do you believe everything else in every commercial that you see on TV?

Granted, there are rare exceptions to the 3000 mile myth. However for 99% of the synthetic using population a 3000 mile OCI is nothing more than a waste of money.

It's up to you though. You can believe those dozens of people who change synthetic at 3000 miles, or you can believe what you read from some of the experts on this board. It's your choice.

3,000 is a waste with dino, let alone synthetic.
