My engine is pretty worked, 3/4 cam, bored 2.3mm, machined & balanced L28 pistons. high compression. would this change what i should use? ----- Original Message ----- From: Terry Rudd To: [EMAIL PROTECTED] Sent: Thursday, 27 March 2003 7:31 PM Subject: RE: L20b oil Dang it, I missed a critical "not" in this sentence,  it should have read: Synthetic oils are "not" all that suitable for the L series -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Terry Rudd Sent: Thursday, 27 March 2003 7:16 PM To: [EMAIL PROTECTED] Subject: RE: L20b oil Rick,   If it's only used on the street and the occasional trip in the country and it's a bog stock to medium warm L20B and/or it's a high mileage unit with worn valve guides but good seals then in my humble opinion you can't go past Castrol GTX (i.e. the original blend). GTX2, Valvoline XLD etc are OK but they thin out and break down in the second half of the change cycle. GTX will stay good up till around 80% cycle in a warn L series engine. If some of my conditions don't apply eg you hill climb or autox etc then you're looking at a different grade and quality of oil, probably a single grade would be more suitable eg Penrite 30. Synthetic oils are [Terry Rudd] not  all that suitable for the L series, although some ppl have good results from Shell Helix.   Heath mentioned BP Coarse + - good oil that and also very suitable for the L20B, in fact it's one of the few "petrol vending company" type oil products I've ever used in 30+ years of motoring that's done the job to my satisfaction. --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[EMAIL PROTECTED]/ --------------------------------------------------------------------- --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[EMAIL PROTECTED]/ ---------------------------------------------------------------------
