Can you use 5W20 instead of 5W30 motor oil?
For sure, fuel economy will be degraded if you use the higher (30 weight) viscosity. But, the statement from Ford also implies that use of oil other than 5W-20, such as 5W-30, will reduce the service life (“durability”) of the engine.
What kind of lubricant does Ford 5W 30 A5 use?
Ford-Castrol MAGNATEC 5W-30 A5 has been developed for use in Ford vehicles that require a 5W-30 lubricant that meets Ford WSS-M2C-913-C or WSS-M2C-913D specification standards. Check your owner’s manual to see if this product is suitable for your vehicle. Delivering superior performance under extreme cold start up conditions.
What kind of oil do you use in a Ford?
In that specification, which is contained in the Owner’s Manual, Ford states: “5W-20 oil provides optimum fuel economy and durability performance meeting all requirements for your vehicle’s engine.” For sure, fuel economy will be degraded if you use the higher (30 weight) viscosity.
Why do OEM manuals advise 5W-20 and 0W-30?
In these cases I suggest a switch to a different AMSOIL Signature Series oil from among the the 0W-20 (product code ASM), 5W-20 (ALM), 0W-30 (AZO) or 5W-30 (ASL). In most cases that product switch will greatly improve or resolve any oil-formulation-specific consumption problem, without being detrimental to protection or performance.
Why is 5W 20 oil recommended in OEM manuals?
We know that even OEM Lubrication Engineers do not agree with Ford and Honda’s calling for a 5W-20 oil, because the engines are designed for 30-weight oil, and engineers believe that a 20-weight oil will decrease engine life . (See 2007/2016 note below for detailed explanation.)
Can you use 5W30 oil in a 15w40 lawn mower?
The real problem with using 15w40 in place of 5w30 is the increase thickness of 15w40. In newer, low mileage engines it is too thick to properly lubricate tight clearances in areas such as VVT (variable valve timing) components. Especially during cold starts.
What kind of oil should I put in my new Ford?
Since both HONDA and FORD Warranty their NEW cars for ONLY 3-years or 36,000-miles the reduction in engine life expectancy is not a factor. By contrast Mercedes-Benz recommends use of ONLY Synthetic Motor Oil that is at least SAE 5W-40! This is a recent increase in recommended viscosity from SAE 5W-30.
What kind of oil does a Motorcraft 5W-20 use?
I’ve always run Motorcraft 5W-20 and changed it at 3,500 mile intervals using an FL-820S filter…. my truck has alwasy ran good and quiet. I was watching a makuloco video on oil pressure testing the 5.4L and he highly recommends owners of 3 valve 4.6L and 5.4L motors to use 5W-30 oil.
