syntec blend 20w50? in a turbo car?

[God Bless the Black Top*]

hey guys,

started using castrol syntec blend in my 4E fte. i've used the full synthetic oil (5w50), but oil would really just magically disappear. before i made the synthetic switch, i had all seals replaced, so i couldn't figure this out? is the 20w50 to thick for my turbo to get it's feed safely?
since i've started using the syntec blend, my oil level hasn't dropped. and i'm getting a strong pull in the torque band. any experience would be helpful.


thanks,
nick

5w-50 is too thin and hence why it disappeared, not made for our hot climate
the 20w-50 would work good with no disappearence unless u r burning oil or overdriving your oil

^^i thought that much, but ppl have used 5w50 in the 4e and not lost any oil?

i'm not sure if this engine was rebuilt in japan?

If you're losing with 5w50 but not with 20w50, it could be that your rings are slightly worn, or some other seal is leaking oil only when cold.

5w50 and 20w50 are exactly the same at operating temperature (~100C). The "W" really stands for Winter, i.e the oil's viscosity when very cold (sub zero temps).

thanks meng, clears things up a bit.



cos i was wondering why would they shelve 5w50 in T'dad when it's too thin.

to catch un knowledgeble 2NERS, the first time around, PPL tend to think, once they c "syntec" the mentality is "boi that is top ah the line oil" so i guess u learned the hard way....

"5w-50 is too thin and hence why it disappeared, not made for our hot climate

meng,

read a little before you post please. i used syntec blend as a solution to the FULL synthetic being lost. syntec blend is rated at 20w50.

^ .... This is an untrue statement ..... It has nothing to do with our climate ... This is a multigrade oil that has a very thin viscosity at startup and the viscosity thickens as the engine is heated up .... Remember, the engine works with its own temperature and not the temperature on the outside .... If the engine has some wear and tear, then you will tend to burn oil ... hence the disappearance ..... If you were to use this oil in a new or relatively new vehicle, the oil will perform normal .....

are you a pendejo how could the viscosity of an oil increase as the engine temperature increases, check back your facts!!!!

Please read something before you all continue with the argument...

[Dave]

tolerances must be very tight to run such thin oils and not have some disappear

^^ I agree, right now I am running 10W30 Mobil1 (Synthetic)

However, I have never touched the engine and there are no leaks, etc. I have been monitoring every weekend (3 weeks now) for any change in the oil level. Thankfully, no change since...

[ninjaboost]

I have found that on the older engines the Syntec (Mobil in this case... never used Castrol due to something I read here... http://72.14.203.104/search?q=cache:rpl ... secret.htm )

My preference for most of my vehicles is the Shell Semi-Syntec (Blue Bottle)

When I rebuilt my 4E I used Mobile for a while with none of the issues I had before but when funds ran low I went back to the Shell and haven't changed since..

Narend is running Kendall 20W50 in his 2nd Gen with no problems

Here are the specs:
Kendall GT-1â„¢ High Performance Motor Oil is a premium quality
motor oil specially designed for use in gasoline engines
operating under high temperature or severe driving conditions,
as well as in competition engines and high-performance street
engines. It is formulated to provide excellent resistance to
viscosity and thermal breakdown at high temperatures and to
minimize the formation of engine sludge and varnish deposits. It
provides outstanding wear protection, including protection of
turbocharger bearings in high-performance engines, and also
protects against rust, bearing corrosion, and foaming.
Applications
GT-1â„¢ High Performance Motor Oil is recommended for use in
passenger cars, vans, light trucks and sports utility vehicles
under all driving conditions, as well as in competition engines
and high-performance street engines. The SAE 20W-50 and 50
viscosity grades are fortified to provide extra wear protection
and foam resistance for use in racing applications. The SAE 70
viscosity grade is specially formulated for use in nitromethanefueled
drag racing vehicles. The SAE 30 and 40 viscosity
grades are suitable for use in older vehicles where use of a single
grade motor oil is recommended.
GT-1â„¢ High Performance Motor Oil meets or exceeds the
requirements of:
• API Service SM (SAE 10W-40)
• API Service SL, SJ (All except SAE 50 & Nitro 70)
Outstanding Features
• Excellent resistance to viscosity and thermal breakdown at
high temperatures
• Protects against engine sludge and varnish deposits
• Outstanding wear protection
• Excellent rust and bearing corrosion protection
• Low volatility for reduced oil consumption
• Excellent low-temperature pumpability for cold starts
(multigrades)
• Good foam resistance
• Formulated for engines equipped with turbochargers

^ What kind of silly question is that Do you understand how Multigrade Oils work or infact do you know what is a Multigrade Oil
