V10 Motor Oil

You will get all kinds of comments here, so I will start. I have driven our Ford V10 Triton over 80K miles so far, and have always used full synthetic oil, generally 5W20 Castrol. As far as the mileage goes, the oil weight is not going to make much difference.

While not as many miles we have only been 36K in ours we live in So. Cal where everywhere we go is either up or down a hill to any distance! :B Like Johno02 we have run the full syn that came in it followed by Castrol full syn 5/20 for all those miles. We run close to GVWR/GCWR on most trips including high heat 100+ in the desert never an issue.

I feel that the synthetic oil gives better protection for this engine, consitering that I sometimes need to run the higher revs for extended time, especially for long grades. I have been told by folks that know engines better than I do that the climbs do not hurt, just to try and keep it under 4000 rmp range but occasionally higher is OK. I understand that this engine develops max horsepower up in the 3500-4200 range. I feel better protected with the synthetic oil , and not having to worry about oil changes as often. This is all IMHO, and I will not get upset if anyone disputes me. I will just continue to do as I please, and let them do theirs.

A v10 has a small bore and a very long stroke. If you want to help you should give correct information.

I have never used anything lighter than Mobil 1 5w-40 and have used 15w-50 for the majority of the 50,000 miles I have put on my MH. It's running as fine as when I bought it with 30,000 miles.

You guys do realize that in other parts of the world, not subject to US emissions laws and corporate average fuel economy, that same V-10 engine is specified to run on 5W-30 and 5W-40 oils.....

And as point of discussion, mine has run a very happy life (based on real oil analysis) running on Rotella T6, as do almost all of our engines.

No they haven't. The recommended oil for my 2000 V10 was 5w-30.

I've always used at least a 5w-40 in mine as well as a lot of miles with 15w-50 (Mobil 1). 50,0000 miles later things are running as fine as when I bought it.

Second question about slides. Again IMHO. We park at home whenever we are not on the road, and have toppers over our slides. If the weather is going to be bad, storms or snow, we usually keep the slides in. No worry about the mechanism, as both slides are hydraulic, and the rollers are protected underneath. more worry about weather exposure for the canvas toppers, and seals. and/or leakage around the tops of the slides.

I use MC 5-30 syn blend the most important # is 5 as when you start need oil moving instantly. been told by lots of people 20 or 30 dosen't matter, i use 30 a far as living in Sfla(more heat)

My owners man said 30 its a "98"

i use 5W-20 Mobil One in my V-10. I would never use any weight other than that which the manufacturer recommends. Technically if there is an engine failure during the warranty period the and a different weight oil is discovered the manufacturer could deny the claim.

I would use what Ford recommends in the manual. I use 5w-20.
