[quote name='Sinful7' date='Mar 16 2005, 12:02 PM']I run synthetic ... Some of the significant bonuses are a higher temperature tolerance and a stronger resistance to film shear. Film shear is the point at which the basic coating of oil molecules are torn from the surfaces they cover - the resistance means less chance of engine seizure due oil system failure.

And hopefully more resistance despite some fuel dilution, which I suffer from alittle between oil changes.

 

I use Castrol GTX 10W40 in the car.



Sex Grease in the bedroom.

 

Halvoline 10w30.

 

Amsoil 20w50 and Amsoil premix

 

I'm using Neo oil. its a synthetic blend. works great. 20/50 every 2,000 miles as well

 

I am looking at moving to synthetic. Is 10-60 to wide? I'm thinking it is but it's what someone I know is running and they say it's fine.

 

Motul 300v competition 15w 60 (100% full syntetic)

whit motul permix

changed every 2k miles

 

i change my oil ever oh.... 500 miles pays to ahve friends working at jiffy lube

 

[quote name='boostincoyote' date='Mar 14 2005, 02:19 PM']hey guys im new and was just wondering what oil is preferred among TT 13bs. Ex. synthetic, non-synthetic, what oil weight according to mileage ex 15w50 and brand mobil, motul, castrol etc. thanx i appreciate as many responses as possible

The responses have been interesting, but not really useful. I have used the cheapest oil I could find (10-30) and I got 118,000 miles (original clutch as well) out of my wife's '94 before one of the rear apex seals let go.



It would be more informative to also list the mileage you guys have gotten out of the 'super wombat' oils that you are recommending.



Obviously, I am biased towards cheap stuff, but I try to change the oil between 2,000 and 3,000 miles.



I got the engine was rebuilt byKD Rotary when they were in Nazareth, PA.



'94 Mazda RX-7 122,000 (Wife's toy)

'95 Volvo 850 201,000 (My driver)

'03 Toyota Matrix 38.000 (Wife's driver)

 

thanx guys for the feedback very useful
