Shell Rotella T6 Synthetic oil anybody using this?

[CARGUY40]

I heard too much good about shell rotella t6 synthetic so i gave it a try. I went to walmart and got about 5quarts of it for $27 tax included! I switched my oil from mobil 1 syn 10w30 to Shell Rotella T6 Synthetic 5w-40 for winter time heard this oil is awesome and i read alot about how tough it is especially for turbos and heat!

My car is a 92 eagle talon tsi awd 4g63 near stock 6bolt with moderate mods sees max 24psi of boost and high rpms here and there. I do plan on switching when summer comes to 10w-40 or 15w-50 cause i think 5w would be thin but i hear people run 5w-40 yr round?

The difference i saw was my lifter tick was pretty much gone with the shell oil and car felt and ran smmother but with mobil 1 10w30 it would tick on cold start for like 10min and would go away if i get on it or drive for a while and the ride wasnt as smooth but the bad i noticed oil leaks more in the same area with the shell 5w then with the mobil 10w i guess its because of the weight?

Here is the full information about this oil= http://www-static.shell.com/static/c...rotella_t6.pdf

Don't worry about t6. $26 though? Ouch, its $19.50 at walmart here.

My Walmart sell it in a 4 quart jug for ~ $20

 

[CARGUY40]

Well is it too thin you think to run it when temps are above 60f cause alot of people with a 4g63 motor are running 10w-15w-20w in there motors and say 5w is way too thin for temps over 60f? But i thought thinner weight is better on cold startup because most engine wear occurs at startup when the oil is too thick to lubricate properly?

$19.50 is for 4 quarts, excluding tax. He wrote that he bought 5 quarts, including tax for $26.

 

[CARGUY40]

Correct i did say that because shell only sells it either in quarts or a 3.785l and my car takes about 4.3-4.5 quarts is why i bought the extra quart.

I'm not a big fan of using RT6 in a highly-boosted gasoline engine. RT6 uses a large amount of magnesium in its additive package to get detergency. If your engine is consuming oil through the combustion chamber, the magnesium can cause deposits that in time will make the engine more prone to detontation or preignition. Oils for boosted gasoline engines should use all calcium-based detergency, or very low magnesium content.

 

[ltslimjim]

Harman, I didn't know that about magnesium vs calcium. I find it funny if that's the case, that T6 advertises specifically on the bottle for 'exceptional deposit control' etc.

 

[rslifkin]

Unless the engine burns a lot of oil, I don't think it's of significant concern.

I think they're talking about carbon deposits, not metallic ash.

Yep, that's why I put the qualifying statement "if your engine is consuming oil through the combustion chamber" in my note. But why take chances with an expensive, highly-stressed engine? You can save maybe a buck a quart by using RT6 instead of Mobil 1 0w40, but you're using what is primarily a diesel oil in an extreme application where a dedicated gasoline oil would be a more optimal choice.

Still nobody answered my question=Well is it too thin you think to run it when temps are above 60f cause alot of people with a 4g63 motor are running 10w-15w-20w in there motors and say 5w is way too thin for temps over 60f?

Even a 0w20 is thicker at room temps than a SAE 60 is at operating temperature

No, it is not a problem, not even close. A conventional 10w40 might have minor shearing issues but not a synthetic like T6

They should try Eneos 0w50 if they have the guts for it

The w-number only applies to temperatures below ~0F. Since RT6 is a 40-weight it will have the required viscosity at operating temperature. Lower w-numbers means that the oil will flow more quickly through the oil system to lubricate engine parts at subzero temperatures.

 

[CARGUY40]

What is a good 10w-40 oil that would be as good as shell rotella t6?

 

[A_Harman]

Mobil 1 High Mileage 10w40 is really good: comparable viscosity to RT6 and an additive package optimized for gasoline engines.

 

[Hoosier_Daddy]

T6 is SM rated for gasoline engines as well

i'v been using the t6 in my turbo honda for a while now. holds up to heat very well. i don't see any negative side effects using it. and i have been running it all year round even in -15c temps.

previous to the T6 i was u sing RP 10w40. it is also a great oil but the cost is keeping me away...
