Synthetic Oil Comment---Bad News??

[Radar]

I ran Mobil 1 all last summer. Not a drop leaked. As a matter of fact, I think a few weeps I had the year before actually leak less now. I am very satisfied with the Mobil 1.

Clear as oil :crazy

sounds like my attempt failed but, it was worth the try, right?:eyerole

 

[Twin_Turbo]

I understand what you mean

No not at all,
I greatly appreciate the explaination as I'm sure many others do.
It really makes sense, just makes my head spin.

I would also like to add that I changed over to Mobil 1 in my 97 RAM 4x4 truck at 35-40k miles.
I now have 55k and have not seen anything dripping that wasn't before.
So at least in my case it has not caused any trouble.
Matter of fact, it has been in the low teens each morning the past few days so I'm sure this has helped in the easier starts.
Just wish I could get started at these temps :s

I love to read the threads on oils and filters. This one was another good one and informative. I only wanted to comment on the use of Synthetics and new engines. I recently purchased a BMW X5 4.4i. My first oil and filter change will be done when the electronic monitor dictates. It usually is required around 14-15K miles. I now have about 10K miles on it. As I am told, BMW uses pure synthetic oil in their motors.

Also, I have been very fortunate with all the motors I have built or bought. No long term leaks, until this last one, which I built and has a slight rear seal leak I don't intend to fix it until I rebuild it. This is the first motor I have broken in with standard oil and run synthetic oil specifically.

I was very reluctant to use Synthetic til I tried it.
In a Motor Home with 68k now 77k no leaks, less oil use, lower temp. In 2 Jeeps with 6cyl at 89k and 92k no leaks, less usage, not sure about temp. Both have 102k and 113k. In my '86 Corvette changed at 98k now 110k same result.
The stuff is great. Mobile 1 with Pure-one filter, soon to be K&N on all.

is pure one really that good? i use Fram on both my cars and they seem to be working fine

 

[Twin_Turbo]

The FRAM is about the worst filter out there. The cheezy paper contruction makes that unfiltered oil can leak past the valve in the filter (the end caps are paper and the rubber anti drainback valve seals against these).

I use a tall style System one oil filter, no need to buy new filters and I don't have to take the filter case apart to see if there's metal shavings in the filter.

It has a fine steel gauze filter that can easily be cleaned.

I had long style WIX before this one and was very satisfied.

no more Fram for me then .......i just thought that since it was made in Israel it's a decent quality oil filter........thanx for posting this

Wow, that was some oil filter study. Check out the ad for Mobile 1 using an 86 Vette. I was cruising Ebay today and came across it.

Heyspike,
The synthetics do hold up better under high heat conditions. There are several articles on the subject not just for vette but other applications as well. I'll choose Mob 1 or the other synthetics, any day, over conventional lubes, particularly here in fla.
Merry Christmas Guys!

Hey guys,as an observer on this post I was wondering how often you change your oil when using synthetic. I started using it in Lori's car (98 Cavalier) about 6 months ago and I have been changing it out between 5-6K. She puts so many miles on that car, using regular oil I would be changing oil in her car about every 6 weeks!

Thanks........ Dave

 

[TomsToy]

between changes

6000 on mine between changes

Sounds like she does a lot of highway driving ?
I would think this would allow you longer times between changes vs city driving.
The engine isn't under the same stresses.

Thanks Guys. She does a LOT of highway driving. I should be good with 6000 mi intervals.

I think it's fairly well established that you can go 6k miles or more between OIL changes, but still make sure to change the FILTER every 3k miles. I change oil in my daily driver (96 Legacy Outback) every 10k miles, but filter every 3k or so. 130000 miles and no problems other than the leaks those cars are known for anyway (see, Vettes aren't the only ones with legendary oil leaks!).

[Interceptor430]

yea, my owner manual says 7500 mi for non-dusty highway miles....and that's on Dino Oil. (2000 Silverado).
I'd think the Synthetic could easily go for 7500 in the same conditions...but it's all a matter of what/who we REALLY believe.
I still run the Dino Oil, change it myself every 3K for under $10,
so it's not too much overkill/waste $ wise.

 

[Heyspike]

Having never changed just the filter on any car, I have a question. How much oil is going to leak out when the filter is removed? Probably just a little, but I would like to make sure.
Thanks--John.

 

[rrubel]

I haven't yet changed just the filter on the Vette (only put 2500 miles on it) but on the Outback I get very little - between the filter and what drains out I have to add less than a quart.

You can't go wrong with the synthetic oil. I've been using Amsoil for 10 years. (the first synthetic oil made) I have never had a problem with it, nor have I known of anyone else to have a problem with it, leaking or otherwise. In fact, in '94 I put it in my brand new Harley right after my 500 mile check-up, and the dealership did it for me. They were reluctant of course because they want their product in it, but the Amsoil guys explained and answered their questions and doubts. Amsoil even warrants your parts if anything does happen due to the oil. It is 100% synthetic. I use it in all my cars, trucks, and even small engine equipment. The Jack Nicklaus Country Club I had worked at uses the same oil in their entire gas powered fleet, including the company trucks, club cars, (which get rebuilt all the time), their small engines, etc. They buy the stuff by the 55 gallon drum.
Not using the synthetic oil on high milage and rebuilt engines is a myth, the oil definetly helps keep it clean. As we all know that every time we turn the key in the car, deposits and grindings come off the parts. The synthetic oil coats those parts for up to a year, even with the car sitting that long. Other advantages are longer oil change intervals, vehicles able to run up to 20 degrees cooler, parts protected, doesn't break down. I been so impressed, I became a dealer. I don't push getting the accounts like I should, I only continue my dealership to get the discounted prices. Hope some of this info. helps with the doubts and concerns, and I apologize for the length.
