Castrol Oil and Sludge Build-up

[Brent]

I think that guy HOT FISH needs to read and understand more of what he is saying. IMHO he is just a rep, and has no right to educate us and  to stand for castrol if he has not even check on the data specs of other oils. And to make the story more interesting there is OIL ANALYSIS which he should also tackle. Maraming grey areas statements nya. How may he say Castrol is the best when he's got no results to compare? He actually destroyed himself and castrol, when in fact, as everyone could agree, could be an opportunity to gather and use feedback to improve the product and customer relations.
He sounds opinionated.. and to state na iba ang formulation ng castol US and castrol Ph... may choice pa ba tayo? :violent1: :violent1: :violent1: :violent1: :violent1: :violent1: :violent1: :violent1: :violent1: :violent1: :violent1:
Bili na bila na Castrol EDGE ni HOT FISH. 

Ang G-Castrol nga finds ways to improve more on the sludge prevention, which is (i forgot the other EU makers) typical of VW, AUDI and the others... Kaya nga may Manufaturers' rating recommendation sila. And G-Castrol meets the standards.

Bakit hindi nalang nila maging kautong din ang NB para makareformulate sila ng Modifiers? ay.... repackage nga lang ata mga castrol dito... galing US? mukhang galing sa...

Sayang.

The Castrol formulation for Philippines comes from Singapore, their Southeast Asian regional office as it states in their bottles sold locally that it is manufactured in Singapore. I actually find it weird for them having different formulations for different markets, because a good oil should work for any market whatsoever.

As for the sludge prevention, it is because EU automakers require long drain intervals to go with their extended service programs. So the oils that have their approvals must pass their tests.

When I used Magnatec it was 10W-40. While the owner's manual calls for a 5W-30, my engine is no longer new and pretty much modified and so I've been using 5W-40, 10W-40 viscosities. Ever since I've stopped using Castrol, I never experienced sludge again.

the use of thicker than recommended viscosity might have also contributed to sludging. I used 10W40 oil (Motul CRDI) on our Isuzu Trooper (which should only be using 5W30 or 10W30). its oil got thick and black after around 6000km of running, and it gave out black emissions more often. when I changed oil again using the right viscosity (5W30), the black smoke became less frequent and it seemed to run smoother.

Uhm no. The use of Castrol oil was the sole cause of sludging. Since then I've used Liquimoly 5W40, Mobil 1 0W40, Redline 10W40 and Motul 300V 5W40 with zero sludging.

You never report back to the company and say the bad experience, you switch to better competition instead. Hindi ka naman nila bibigyan ng money-back guarantee eh.

so true!

pero good local reps should be able to answer questions like that imo or at least forward it to the regional office....

guys,

nabasa ko yung thread sa NB. Normal lang lang sa sales rep ng castrol na protektahan yung product niya. kaya kung anu-ano ang palusot niya pati yung sabi ng boss niya. hehehe! magaling lang ang castrol sa marketing and promotional activities pero with product quality wala silang laban.

nabasa ko rin na hydrocracked lang yung Castrol edge according dun sa sales rep. Question lang guys, ang hyrdrocracked oils ba is considered Fully synthetic? kapag mataas ba ang viscosity index ng oil pwede mo na itong tawaging fully synthetic? medyo magulo kase yung sabi ng sales rep ng castrol.  db dapat yung type ng base oil ang tinitignan para masabi mo na fully synthetic?

hYDORCRACKED (purified  group II) is Group III classification
the higher Group IV is PAO base
Group V is Ester based

viscosity index pertains to the thickness of the oil, whatever group it may be.

Do you trust that kind of guru? :violent1:

As I've repeatedly explained in most oil topics here on Autoindustriya:

Fully Synthetic = Hydrocracked Mineral Oil, it's more of a "marketing" term for highly refined mineral oil with a better than average additive pack.

100% Synthetic = Or at least the base oil is declared on the packaging (Redline doesn't state 100% synthetic but states that it is Ester oil). These are the only things that I will use in my engine which are "REAL" synthetic based Group 4 (PAO) or Group 5 (ESTER) based oil.

I will not trust anyone from castrol even the brand itself. hehe! mali kase yung mga tinuturo nila. I will only use real synthetics instead of using castrol edge and even magnatec nila.

Salamat po!

my first ride which I got second hand has a lot of sludge built up and when we brought down the cyclider head, all the valves (stems and valves) have caked built up of some crystal like grayish materials. I ended up repalcing the whole cylinder head with valves and camshaft from banawe surplus shop. (aside from water jacket corrosion cause by wrong type of coolant) I believe the fist owner is using oil additives ever since. This is what an oil additive
can do. It is much safer to just use the oil as it is, no additives.

This thread is about Castrol oil causing sludge not oil additives.

if you really believe Castrol oil is the culprit and you have all the evidence to prove it, then why is there nobody filing a class suit against Castrol oil? Or has anybody doen it already?

Well I caught the sludging in time for me to correct it without any damage being done to the engine. So I really don't have any intention of suing them but at the very least I'd like other people to know about this problem. A lot of maintenance shops know about Castrol oil producing sludge. I chose to just move on and use better quality oils.

[tip_tipid]

well that is good. I haven't been a fan of this so called performance motor oil used by rally team and so forth. I still stick to my ever tested Super Shell sold in the Philippines. By the way, not all Shell Oil Products types are available worldwide, or they may have different names?
