Synthetic oil?

[88fiveohGT]

I'll be freshening the bottom end this weekend and was wondering if it would be worth it to switch to synthetic? Right now i run 10w40 Valvoline if it matters.. thanks for the input.

I find it hard to believe anyone would tell you not to use synthetic over standard petrol oil.

[88fiveohGT]

so its worth the extra money?

I use Mobile 1 Synth. If it is good enough to come stock in Vette's Ferrari's and a shit load of other cars I cannot afford, it's good enough in the POScort and the Rustang. Plus, my Escort has 166k on the clock and does not leak or burn any oil. I change the oil every 5k. Good shit Mobil 1 is.

Use it, but use it after break in.

What does freshening the bottom end include? A shot of Febreze? Or a few dryer sheets?

Synthetic is good stuff, especially on Open Track Cars. Look into Royal Purple or Amsoil. Before you buy Mobil 1.

Mobil isn't bad stuff, but the others deserve a look.


check this out.

Mobil Oil recently reported the results of simulated hot-weather
performance with its Mobil 1 synthetic as evaluated by a standardized,
grueling engine test known as the Olds III-D. In this test, an
Oldsmobile 350" V8 engine is run for 64 hours at a 100-hp load and 300F
crankcase oil temperature. This test is designed to measure an oils
ability to resist oxidation and evaporation (and consequent thickening)
at high temperature. (If it seems odd that oil would *thicken* at high
temperature, consider the analogy of heating a pan of cold syrup on a
stove. At first it would become quite thinner, but if left for, say,
several hours, the resultant evaporation would cause the syrup to become
progressively thicker.) In order to qualify for the American Petroleum
Institutes top "SF" rating, a motor oil must pass the III-D test. This
means that it can thicken to no more than 375% of original viscosity at
the end of 64 hours of continuous running. Mobil states: "To test the
extra stability provided by the Mobil synthetic oil, we decided to run
the III-D *for 128 hours*...double its normal length...and without oil
drain. The Mobil 1 synthetic easily passed the test under these brutal
conditions, thickening only an insignificant 20%. For comparison, a
high-performance premium conventional oil was tested under identical
conditions. That test had to stop at 96 hours; the oil had turned
solid. Another premium conventional oil forced the the test to stop at
112 hours, well before the end of the scheduled double length." Amoco
Conducted an identical double-sequence III-D test on its Ultimate 5W-30
synthetic; it also passed the test with flying colors, thickening only
18%.

Has anybody seen else seen that WalMart now carries Synthetic of their own. 5 Quarts for about $12? I dont know if I want to try it but someone might. FYI when I was there they only had 5w30, 10w30

#1 Valvoline, don't get me started.
#2 10w40? Hello dirty engine.
#3 Supertech synthetic (walmart) is made by Warren. It's a group III oil and a great performer for the price. More on the group thing later
#4 www.auto-rx.com as per the directions....trust me
#5 http://www.caranddriver.com/article....&page_number=1
#6 Personally, I'm an AMSOIL guy. Contact Phranquy to get some.
#7 If you really want a 40 weight, then switch to a 5w40. Much more shear stable and robust. You engine will be much cleaner in the long run.

I wonder whos' brand they rebadged.

All you ever wanted to know about oil, filters, additives, etc.

Bob is the oil guy

Mobil 1 Syn goes on sale and is easy to find.

Warren's.

When Warren sells it the stuff is called Mag1.

Mobil1, Red Line, Royal Purple, AMSOIL, etc all give similar enough performance that you couldn't tell the difference to the average person. Just be happy you use better oil then 95% of America.

Something to read about oil in general, may open some eyes. http://63.240.161.99/motoroil/

I'll be putting German Castrol Syntech 0w-30 in my motor when I change oil again. (true Group IV/V Synthetic not a blended Group III like american syntech)
