Where can i get this type of oil at reasonable or cheaper price? If not convenient to post here,can pm me. Thanks

This interesting article is post by Dr AEHaas from BITOG. Somehow I missed this paper presented at the Powertrain and Fluid Conference of Oct. 2005: Evaluation of SAE 0W20 and 5W20 GF-4 Prototype Formulations in Severe Taxi Fleet Service, Amanda Damen, Petro-Canada, Nigel Broom and Rolfe Hartley, Infineum USA LP, and Michael Riley, Ford Motor Co. My review: The Las Vegas taxi service is considered the most severe for testing high temperature fluids. Four taxis were run with 0W20 and 4 with 5W-20 test oils for 100,000 miles each with a test oil having only 0.05% phosphorus. This is to test the newer GF-5 pending specification. All engines were then broken down and tested for wear. Oil testing was done at 5k and at 10k miles. Each oil was specified to run only 3k miles by Ford under these

was thinking of using Royal Purple 5w20 for my coming 20k services.... any bro/sis expert in oil can advise.... thanks in advance.....

hi, going for my 44k servicing soon, can use 5w20 engine oil on my 2yr old 2L Honda Stream? never go North to chiong, only for local use, engine rev to 4k rpm max at times niah... thanks

As above, any tried before? Need your advise. By the way i am on SS7 5w20.

Hi all, been searching high and low the net for this, but it only listed Jap makes. Its from Autobacs and is in Jap. I got it translated using Altavista Babelfish Translator...so if any one can read Jap, please help to clarify. Here's the link: http://babelfish.altavista.com/babelfish/t...eceeedfgfdffg.0

Hi Everyone, I'm driving a 5 year old Nissan Sunny Manual and I've been using Mobil One 5w30 / 10w30 without problems. I'm thinking of trying out the thinner 5w20 by either Royal Purple or Schaeffer. Do you think it'll be a problem since my car is already 5 years old? Will the thinner oil cause the engine seal to break and leak? Anyone have any experience so far on 5w20?

@ https://www.fleet.ford.com/FFH/Why5W20Oil05...asp?News=Rental ""5W-20 oil is a thinner oil with lighter viscosity that creates less drag on the crankshaft, pistons and valvetrain. Additionally, the oil pump can pump thinner oil more easily, improving oil circulation. Any increase in fuel economy may not be noticed by the average motorist. Machined internal engine parts are more precise than the parts of 20 years ago. This means that clearances between moving parts are smaller and more exact. Thinner oil such as 5W-20 can flow more freely through the engine while still filling the spaces. Thicker oil is harder to push through the spaces between the parts. This causes the oil pump to work harder, which in turn increases oil pressure while simultaneously decreasing oil volume. A lack of oil volume results in a decrease of lubrication and cooling, which may decrease engine part life. The lighter viscosity of 5W-20 oil flows faster at start-up compared to higher viscosity oils, which helps reduce engine wear in critical areas by lubricating parts faster. Valvetrain components at the top of the engine require immediate lubrication at start-up. Oil additives are not recommended as noted in the owners manual. The American Petroleum Institute (API) certifies that oils such as Motorcraft 5W-20 already contain the necessary additives for friction, detergent, etc... The addition of additives may interfere and react with the additives already present in the certified oil.""

Read an article on Web, it said 5W20 qood pumpability in cold weather but increase mechanical wear because too thin the oil. Although it does not shear as much as 5W30 oil but when engine reaches the ambient temperature and it's vicosity will begin to thin out resulting in less protection. Some oil are added with moly to prevent frition and thinner oil has less resistance in engine that deliver better fuel consumption. But thicker oil will give you better protection, So which to choose, better milage or better protection.
