    Buick 401 Nailhead Oil

    The highest octane we have anywhere near here 91, non-ethanol, so that is what it runs. I haven’t had to mess with timing or carb settings at all but I do not get any pinging on 91. I have slowly used up an old 32oz bottle of CD2 lead additive over the last 2 years and am finally out now, but...

    Buick 401 Nailhead Oil

    VR1 so far, the first year with a blue bottle of STP and then last year with a bottle of Engine Restore instead. It does have a lifter tick that comes and goes, usually a long highway drive will clear it out for a bit. So was considering Valvoline Restore and Protect to help with that, was my...

    Buick 401 Nailhead Oil

    Resurrecting this old thread as the car comes out of storage in the next few weeks and will be getting its yearly oil, filter, and lube. Have been wondering if Valvoline Restore and Protect would be a good choice now that it has seemed to be a proven oil? I would likely just continue the yearly...

    2014 3.5 Ecoboost Oil

    Yeah I see that it's actually 6 quarts. And the 5.0 is 7.7 quarts :oops:. And here I thought the 5.4 3v taking 7 quarts was annoying 😅.

    2014 3.5 Ecoboost Oil

    Just about completing my first week of driving the truck as I normally would. Checked the oil this morning before starting and it was not overfilled or gas smelling, which means so far so good I think. I will keep an eye on it, especially as we start getting colder. If increased oil level or...

    2014 3.5 Ecoboost Oil

    That was another thought I had other than going specifically off mileage was do a change in October/November, change in January/February to get fresh oil in half way through, and then again in March/April to get fresh oil in again for the summer. 9-10k miles makes me kinda nervous on one of...

    2014 3.5 Ecoboost Oil

    I do usually around 9-10k a year in the end despite the short commute. Summer doesn’t concern me as much as the truck will stay warm between trips and eventually get a good warming cycle almost every day. Winter concerns me because the aluminum block won’t hold much heat in cold weather so it’ll...

    2014 3.5 Ecoboost Oil

    Probably one of many posts about Ecoboost oil, but wanting to confirm my thoughts. I purchased a very nice 2014 F150 King Ranch with a 3.5 Ecoboost. The truck has 155k miles on it. It has been serviced fairly religiously every 5k with synthetic oil, and is completely silent at startup and...

    Buick 401 Nailhead Oil

    Is the different between the street VR1 and race VR1 the conventional vs synthetic? That’s all I see offered on Valvoline’s site at least. The VR1 I am able to get locally is conventional.

    Buick 401 Nailhead Oil

    CharBaby mentions the additive package on the VR1 and running regular OCI's, which in this case is realistically going to be 2-3k miles on a yearly oil change, perhaps 4k at the most. Are there any concerns with running VR1 at a somewhat regular interval instead of perhaps after every outing in...

    Buick 401 Nailhead Oil

    It does have lead substitute mixed in with the gas at each fill up. Currently slowly using up a bottle of CD2 concentrate, not sure what to switch to when that's gone but its probably 75% full so it'll be a while.

    Buick 401 Nailhead Oil

    I guess I should say that the car has been gone through by a previous owner/mechanic and had most things it could or would need after all these years replaced. Shocks, brake shoes, wheel cylinders, brake hoses and lines, springs, fuel pump, water pump, plugs, wires, cap/rotor, points, etc...

    Buick 401 Nailhead Oil

    Thanks for the recommendations. Is Valvoline MaxLife synethic blend a good choice if wanting try and stave off future leaks? I've used that in the past so slow or stop slow leaks in newer engines and liked it. It does currently have 10w40 in it figuring that it's probably a little tired. I...

    Buick 401 Nailhead Oil

    Curious what would be the recommended oil fill for a Buick 401 Nailhead engine with 98k miles. I am 99.9% certain that internally it is untouched original from 1965 in my knowledge of the car, and there is nothing to indicate that it has had any work done to it. In researching I've pretty much...
