thanks....fellow barbadian:rockon:
if u dont mind me asking...which cam timing marks did u use? (4E or 5E)
rep added for everyone so far
4e timing

seems most bajans use that 4E mark

reason for the 15w40 weight is its a medium priced oil and is also a medium weight with both good cold and hot temprature engine protection. Also because its one of the oils we sell to our customers, so reinforces that we trust the oil we are selling them.
advantages of mineral i find is that it tends to be a bit thicker than that of the same weight synthetic oils which helps allot with maintaining a good engine oil pressure and not needing to play around with the pressure relief valve. for example when your engine is cold and you start it up the oil is thicker than when its warm and you will notice oil pressure drops somewhat.

i highly rate the castrol GTX oil. its very good IMO. used to run noting but that on my other cars until its price became less competitive over here.
im not so fond of Magnatec as its to thin for most turbo applications and i find that it tends to burn quite allot between oil changes.
container = BIG RED drum, we purchase it in 200L or 44gallon drums haha
the forumla that im running is actually a diesel oil as most of the stuff i do on a day to day basis is on diesel engines bar the odd High performance V8 or japper which seem to like it just as much.
no problem
i havnt experienced any issues on big truck ball bearing turbos running this oil so i would say it should be compatible. if in doubt check the manufactures specs. with turbos as long as you have the correct oil pressure and volume feeding to the unit they usually dont have issues.

i run castrol gtx 20-50 and never had an issue...i just change it when it needs changing
however, i live in the carribean (its hot alomst all year round)....u may need something with lower weight for cold weather i suppose

its the same here in the phils. are you using it on a 5e motor? any disadvantege of using it on a 4e motor?

try hunt down the gtx protec, its a bit lower viscosity and more suited to turbo applications at 15w40
more info on the total oil
stuff i run is Rubia 7400
never had issues with 15w40 burning between changes.
only time you will is on a worn high milage engine
back to topic i think lads
isaw a castrol gtx diesel in here. its 15w-40 .
heres the link : http://www.castrol.com/castrol/productdetailmin.do?categoryId=82914749&contentId=6004919
i believe its for diesel engine. is it ok to run? is it the one youre reffering to?

i've used it on a few 4efte engines with no issues
i know it has been used in 5efte builds also...2 cars locally iirc

nah thats not the one.
GTX protec 15w40 is what i would be running, but you may or may not be able to get it where you are im not sure.
best to get the equivilant petrol oil if possible
main reason i use the diesel oil is its what i sell and have on tap so easiest and cheepest for me.
diesel oil is formulated for low rpm, high load situations and also has added detergents in it to help clean the engine which is required on diesels so they dont clog up the oil passages etc for various reasons.
it suits my engine because of the spool up rpm and mainly being road driven it doesnt get revved over 4000rpm on a regular basis. if i do it chews the oil up quite fast and brings the service interval down, 2-3000km, so more regular changes are needed as i posted earlier. i do them very regularly, not something thats suited for anyone who doesnt have a 400L drum of oil handy every day..
cheers

timing mark disscussion
so whats the general consensus? the 4e marks tend to idle higher or lower?
higher would make sense as your theoretically increasing the base timing so idle RPM will rise and you should notice a small increase in low down power but it wont make much difference to top end, it may even drop off a bit in some cases. (small turbo)
@ jorgan.
i used gtx before. very stable at high temps. but in low temps very thick.
@finx
gtx protec is not availble in here. gtx, magnatec and edge are the ons readily available.
i saw a total rubia xt in here. 15w-40 viscosity.gold container.
right now im using castrol magnatec, i think its burning on high temps?

edge is the 20w50 if im correct? thats quite a thick oil so unless your engine has done high milage i wouldn't recommend it.
yea magnatec seems to burn quite allot on turbo applications, yes its due to the heat as well as a few other aspects.
give Rubia 15w40 a try next time you do a service and see what you think.
nah edge is 5w-40 abd gtx here is 20w50. ill give rubia a try next oil change. i observed that magnatec burns when its hot. specially here in out country the daily temps ranging from 31-38'C
