Oil

[umaxman]

Hello all, I was just wondering if you guys (gals) use Synthetic oil? and does it offer any advantages other than longer between changes? Is it better for your engine...etc
I have done a search but didn't really find what I was looking for .
The more I drive this thing the more I like it

Umaxman,

I use synthetic on all my cars. I still change oil every 3,000 even though you can go longer. Synthetic supposedly will give you a bit more MPG because it slipperier and allows parts to move more easily. It doesn't break down under heat like dyno oils do so it's essential for any Turbo engine. I take 14 hour non-stop (except for fuel) trips and want the best protection you can get and I believe synthetic oil will do that.

I use Mobil 1,because of all the good things i've read
about it on this forum. It runs cooler and if you have
a turbo you want something that doesn't break down. I
also change oil every 3000 miles . when I was using
other oil I changed it every 1500. I don't think you can
go wrong with it.IMHO

I also use Mobil 1 and K&N oil filters.
Walmart has Mobil 1 for about $ 4.00 a quart which is half what I would have paid if my mechanic supplied it. Change it every 3000 miles just to make sure I don't void the warranty.

Synthetic oil is in my lawnmower, snowblower, and every car I've had. It is, quite simply, better at lubricating. I don't buy the extended drain periods - the oil won't break down, but it can pick up acids from combustion, so I change every 5,000 miles. I think Mobil 1 is the best readily available one.

Until I got my turbo car I never used synthetic oil, but, NOW I am a "believer" because of all the reasons cited preveously. I use only 5W-30 Mobil 1 with K&N Performance Gold Oil Filter (Part #HP-2009). I am pleased with the results --outstanding performance and improved gas mileage: http://www.ptcruiserlinks.com/forum/...?TOPIC_ID=8131

There are lots of reasons to use synthetic oil, but a turbo is the best one of all! I've used Mobil 1 (and Delvac 1 for diesels) in cars, bikes, boats, generators, mowers, tractors and trucks for years now with nothing but great results. I've only got 6000 miles on my PT, so I'm using the 0W-30 along with a Mobil 1 M1-209 filter. My dealer has no problem using my parts and just charges me their LOF labor. If you've ever seen the difference synthetic oil makes on the inside of a turbocharger, you'll never use anything else. One last thing, make sure that you buy a full synthetic oil and not one of the lower-priced blends that are out there. This matters a whole lot more than the particular brand that you choose!

Happy Cruisin'!!! [^]

How long have synthetic oils been around?
What did turbo drivers do before synthetic oils existed?

Commercially? Since 1929, but popularized for automotive use in 1972 (Amsoil) and in 1975 by Mobil (Mobil 1).

Personally I've been using synthetic oil in all my cars since the mid 70's. Change the oil (and filter) to synthetic the minute I get home after taking delivery. Can't beat synthetic for keeping your engine clean and, IMHO, running better and longer. Turbo guys use synthetic to prevent the oil from coking in their turbo bearings and seals. Cheaper to change the oil that to replace the turbo. If you look inside your engine after using dino oil for a long period of time, you will notice a varnish coating forming on your engine parts. Later on, you will begin to see sludge form/build up. My 84 Caravan engine stills look clean inside and thats with over 160k miles. The mechanic at the dealer was surprised how clean the engine was when I had the timing chain replaced under the regular maintenance schedule. YMMV.

Jet engines, military and civilian, have been using nothing but synthetic oil since the 1940s. A modern military jet engine might get an oil change every six months, the stuff is that good. Your PT engine works hard, give it the best protection available, synthetic oil.
