    Synthetic oil vs conventional oil

    Synthetic oil vs conventional oil? I was wondering what all of you guys/gals use in your trucks? advantages vs disadvantages? I was thinking of switching to synthetic? or maybe a heavier oil 20W50? I am about to do my first oil change since a bought this truck which has a 5.4l V8. I also do alot of towing......

    Cheers

    I would void using a heavier oil on newer vehilce, the tolerances are too tight and will not lubricate properly.

    As for what oil I use, all my toys run on synthetic oil, truck, atv, both engines on my boat.

    The oil doesn't breakdown as quick and provides better lubrication when cold and under extreme temperature....also my oil never really stays in long enough to get dirty... I m on the anal end of the service schedule

    You should sell off all your used oil to a certain "Steve" individual Jack! aka Captain Anal?

    they may not have recommended it as to a cost factor, but its also a preference as well, I work at the Honda dealer (car) in Victoria and we only use synthetic if the customer asks for it.

    I can't speak for engine use, but I ran synthetic oil in my Volvo Duo-Prop leg.

    I'm not sure what is in the new leg - I'll have to ask the mechanics what they used.

    Usually syn is a bit thinner I was also told not to put syn in the 9.9 yammy as well?????Really dont know why , but with the good oil nowadays we use as long as you change it regularlly there isnt going to be any inn effects me thinks.

    if you buy yamalube outboard oil it is a synthetic blend, alot of companies dont recommend it for break but after that you're all good, the main thing is changing it.

    Most synthetics and even synthetic blends outperform and outlive mineral oils. 50 degree farenheit cooler oil temp has me sold on it. Also less oil changes per annum. In a 7.3 powerstroke Diesel the oil annaylsis comes back synthetic all the way, can't hurt a hard working high RPM marine application IMOP[8D] The amount of training Striper Jack has on this stuff and from the miricals he has bailed me out on over the years, enough said, the guy knows his ****.
