Look at the newer Valvoline blue extreme 5w40 oil. Looks pretty good. Image Unavailable, Please Login
Amsoil zrod oil also looks good. Heavy on zddp for solid lifter and flat tappets etc. Sent from my LM-Q710(FGN) using FerrariChat.com mobile app
I think I'll go with the Valvoline blue extreme 5w40 oil....You want zinc at at higher level but not too high and this looks perfect. 0w40 is too thin in my views.....anyone else
Z-ROD® Synthetic Motor Oil does not state any zinc or zddp levels and the tb is lower and also the viscosity is lowwer as well and they only show a 10e30 or 20w50 which is too think on start ups thus showing a lower viscosity at both the 40C and 100C HTHS is lower at 3.6 on the 10w30 and the 5w40 val is 4.0 yes the 20w50 is higher but again too thick IMO
Page 1, https://www.amsoil.com/techservicesbulletin/MotorOil/TSB MO-2007-08-08 Flat Tappet.pdf I currently use Redline in engine and Amzoil in gearbox but will switch to Amzoil in both. Redline is also thinner than the weight would let you to believe so many go up one weight.
Date: 8/8/07 Revision 3: 9/3/13 Product Description: AMSOIL Synthetic Motor Oils Subject: Flat-Tappet and Camshaft Lobe Lubrication Looks dated and no current info on this oil
OK well perhaps they are misleading and, they secretly changed the oil and refuse to update the spec with a new date as it would to expose their deception. Perhaps you exposed them, use something else.
That's racing oil isn't it? Don't think we need that much ZDDP levels and it's really pricey stuff....
Brad Penn makes all kinds of oil products. I have always run it in my Ferraris and in my drag bikes in younger days. Cost $4.25 a qt here in the states. You must be an lubrication scientist, and I'm just giving my opinion.
Ferrari of Atlanta used Quaker State 5w-40 full synthetic in my 348. Never would have guessed that QS would be used.
I contacted Amsoil a few months ago regarding the date of their Bulletin (I had Revision 2 at the time, 5/2/11) and received a reply as follows: “I am very interested in your Premium Protection 10W-40 Synthetic Motor Oil (AMO). I have your TSB MO-2007-08-08, Revision 2: 5/2/11 containing information on ZDDP for the mentioned oil. Please advise whether, as of today, there have been any changes to the figures provided in the Revision 2 dated 5/2/11.” “Thank you for contacting AMSOIL with your question. The levels listed are still accurate in regard to the current formulation. If you have any other questions, feel free to contact us. Ryan Lawrey Technical Services Representative AMSOIL INC. ADDRESS: 1 AMSOIL Center, Superior, WI 54880 E-MAIL: [email protected] PHONE: 715-392-7101 Ext.6093 FAX: 715-399-6531” I intend to use Premium Protection 10W-40, Phosphorus: 1,265, Zinc: 1,378.
There's too many oils they formulate and I think anything over 1300 is too much for a car with catalysts. This is why they reduced the TB and ZDDP levels in Diesel engines to protect the After-treatment system. The Premium Protection 10W40 states nothing about exhaust systems and just about internal engine protection: AMSOIL Premium Protection 10W-40 (AMO) and 20W-50 (ARO) Synthetic Motor Oils are formulated with high zinc and phosphorus levels to provide outstanding protection in both gasoline (SL) and diesel (CI-4 Plus) applications. They are an outstanding choice where high zinc-containing protection is required, such as late-model hot rods that require extra camshaft protection. Late model hot rods? Also states CI-4 plus oils which were formulated for Diesel engines before after treatment systems.....ie; DOC and DPF's. If you were to put this oil into a Diesel engine with after treatment systems it will prematurely plug up the system with the additional ash caused by the extra additives and increase exhaust back pressure which is stressful on the engine. So in theory yes......extra ZDDP is good for the engine but not good for the exhaust. Also the extra detergents used in the CI-4 oils is what causes the issue and degrades the catalyst system in diesel engine exhaust systems and even more on car catalysts as it reacts differently on spark ignited systems than compression ignited. The extra sulpated ash produced and higher TBN are fantastic choices if you don't run a Catalyst system. If you have an older type diesel engine without particle filter and a catalyst, you need a high level of ash and TBN The ash level and TBN follow each other........These 2 values give an indication on the detergent level in the oil which is extremely important in diesel engines because of the high soot level. But there also seems to be some negative effects: Positive: Detergency (and maybe diperseancy) effect Negative: More wear due to high ash content. More sludge build-up due to high ash content. Make sure you get an oil that can provide the best protection without having negative side effects especially if you have any type of exhaust systems
Kind of interesting, first video shows the test he does it for all oils, second and third link shows tabilized results. https://docs.google.com/spreadsheets/d/1J4yGGQQnIX7gZIfT3ga2qJatRfdmFgmaNPLqpmrxQnE/edit#gid=0 https://docs.google.com/spreadsheets/d/1fbb9qtL-yWlzDPLzvxzpF01gRRtH8fKxeVtXt6HPpgg/edit#gid=0
I use Mobile One 15W50 in my 348 spider and have been for the entire 13 years I have owned it. https://www.mobil.com/en/industrial/lubricants/products/mobil-1-15w50
