Is it ok to change 20w50 oil to 5w40 oil?

[Iylia H]

sorry for the noob question, but I just got selected by castrol to write a review on castrol edge, from the castrol edge contest. and i think they'll put in their 5w40 oil into my car's engine. and i'm using 20w50.. is it safe to change?

If your engine is old.. it will leak. However my personal suggestion is to use CASTROL EDGE SPORT 10W-60
http://www.castrol.com/castrol/genericarticle.do?categoryId=8264018&contentId=7007302

Alternative is PENNZOIL PLATINUMTM GT 100% SYNTHETIC SAE 5W-50 (API SM/CF)

Cheaper upgrade from yours is http://www.shell.com.my/home/conten...ants/shell_helix/product_range_new/helix_hx7/ RM90 for 5liters pack in Care-four

thnk you, but i will only be able to put castrol edge in my car... as this is part of the competition... as i need to do a review for the oil... the best review will win a trip to nurburgring, to drive an M car with the help of an instructor

just got an email from castrol, they will put in castrol edge 0w50 engine oil...

hey! Congrats! Hope u get to be selected to attend the driving drill in Sepang before heading to Nurburgring.. :top:

Just pour the Edge in, your engine won't die la. It's a much superior oil compare to mineral 20w-50. Wow! didn't know they have 0w-50, that's a wide viscosity range, suitable for cold engine start, yet able to withstand high operating temperature.

If your engine is not suitable for 0w-50, u will notice your engine consume engine oil and will experience drop in oil level.

hey thnx AB.. u took part in the contest also? and as for today, castrol just sent me a new email, stating that they have made a mistake, and they'll be putting 5W-40. And I think I'd be putting this oil into my moms car, which is much newer than my e34. So I will be reviewing the oil with my mom's car isntead.

No problem if u pour it in..but scared u either see ur car leaking engine oil o see blue smoke coming frm the back of ur car..dun worry..check ur engine oil frequently..after tht use back ur 20w-50
