Amsoil 15-40 or 5-30?

I have read on here that the amsoil series 3000 HDD 5-30 has greater wear protection than their 15-40. But we are supposed to be running 15-40... ..... I am not by any means an oil expert just your average joy blow... . Isn't the amsoil 5-30 a thinner oil? If it is alright to run their 5-30 i would rather do that if it provides better protection... ... .

Go to Amsoils web site and read all about it http://www.amsoil.com/ Personally I would run the 15w40. I use the Series 3000 5W30 Synthetic Heavy Duty Diesel Oil.

Thanks for the reply, and I no it is just your opinion... ... . but why do you suggest the 15-40, and you are running the series 3000 HDD 5-30?

Jason,

I ran the Amsoil 15W-40 for the first 105,000 miles on my '94, then I went with the HDD series 3000 5W-30 oil. NOw have over 135,000 on it. Both are excellent oils!

You can pick either one of those oils and not go wrong. Amsoil has an engine flush that cleans and disolves some of the slug build-up that happen with petroleum products. If you have a lot of miles I'd suggest using it, otherwise you'll have to change your filter earlier than required. Both oils have an additive that helps dissolve the sludge build-up, but it's not as concentrated as the engine flush. I went with the 5W-30 and a By-Pass filter, and at 7,000 miles I had to change filters, the oil was still good to go just topped it off. Using Amsoil oil analysis program is also a good way to have your oil checked for continued use.
