This has been asked on another forum and wanted to have your opinion on this if you don't mind. Will changing the oil to a thicker Mobil1 5W30 EP weight affect in any way the oil squirters ! As we know the Boss doesn't use them and is factory filled with 20W50. Any downside to using 5W30 full synthetic ! Thx
Many thanks for the quick reply! Unfortunately it's very difficult to get oil shipped from the US as oil is declared a hazardous item (I tried that about 3 years ago). I found only one potential company in the UK from where I could get Amsoil from. Do you have any idea from where in Europe I could get the oil and filter you have proposed? I googled a lot, but I haven't found anything else except the link I mentioned already...
Perhaps you have also answer for the other items which are recommended from AMSOIL for the BOSS engine: AMSOIL Product Recommendations - 2012%7cFORD%7cMUSTANG%7cU
Based on your experience, can you recommend also the other oils and an earlier replacement of them than mentioned in the service manual?
I have read a lot of your postings about AMSOIL and I am interested in your view, if this is the right oil for a new BOSS 302 (first oil change planned after 1500 miles), I will not be that often racing, no mods planned: Amsoil 10W-40 Fully Synthetic High Perfomance Petrol Engine Oil
Important detail, I am living in Switzerland, so from time to time it's pretty cold...
And is there any downside ordering now oil for next couple of years, I mean could the oil get kind of "bad" within the years when laying in cellar?
am interested in trying Amsoil ATF in '11 GT500. gearbox was just rebuilt for1-2 grind but still grinds first shift of the day. Would this be OK to maintain warranty? Where would I get it? thanks. Chris
I know there has been a lot of debate about the oil to use in their GT500. I myself would like to hear what you think the top 3 oils and weight are and where I can find them. I have a 2010 GT500 with 2500 miles on her.
