Engine Oil/Additives for high mileage 3.0
 
When I changed the oil for the first time in my 3.0, the engine had
141,000 miles on it. I used Valvoline MaxLife 10w-30 as the motor oil.


I was wondering what the experts recommend for engine oil for this
motor as well as their opinions on oil additives such as slick-50,
and/or engine flushes to help prolong the life of the motor?

Thanks,

Joe

Forget the slick 50. If the engine is REASONABLY clean an engine flush
using a mild agent like rislone or ATF can be helpfull. Don't use
anything too aggressive, and not if the engine is REALLY cruddy.
At that mileage I'd start looking at 10W40 oil - and do NOT believe
the crap about 10W40 being no good. Just change it reasonably often
and the "red herring" viscosity loss will never be a problem.

In summer I always ran 20W50 in my '88 3.0, and 10W40 in the winter.
Central Ontario, 240,000Km on the car when I sold it, still running
like a champ.(had heads replaced twice due to the "normal" valve guide
issues)

There is no reason to use "high mileage engine" oils such as MaxLife, and
several good reasons not to. They tend to be injurious to polymeric seal
materials in the long run.

A good grade of standard 10w30 is a wise choice.

> as well as their opinions on oil additives such as slick-50,


NO!

> and/or engine flushes


NO!

You waited till you had 141K miles on the vehicle to do your first oil
change? :)

Seriously, do not use the Slick 50 as it can only damage the engine. Stick
to good dino or synthetic oil (Valvoline Max-Life or basic qualifies in my
book) and use a good filter (I use Purolator stay far away from Fram oil
filters). On flushing, this is your call. I have occasionally used the
Kerosene flushes on high mileage vehicles that had not been properly cared
for by previous owners and never had any problems, but I followed the can
instructions to the letter and made sure I drained the old oil completely
before refilling with fresh oil. As I said, I've been lucky here and never
had any gasket leaks or major engine problems develop after doing the
5-minute flush. That said, on vehicles I've owned since they were brand
new, I change the oil and filter every 3K miles so have never needed to do a
flush.

I'm ignorant of the whole Max-life thing....I use syntec in my '66 VW,
but that thing is my baby....for my new cars, I use whatever the manual
says.

If not Max-life, which brand is the best? Castrol Syntec Blend? I'm
not going to use pure synthetic if I'm changing every 3000 miles, it
costs too much.

Unless you drive very short trips that don't allow the motor to get hot or
tow large loads, changing every 3,000 miles is a waste of oil. Mobil 1 can
be purchased in a 4 qt container for about $20.00 at Wall Mart and is go to
go for 7,500 mile changes. Whatever you use go by your vehicle's book to
select the proper viscosity and grade.

7500 miles on an engine that already has 142,000 on it?

I guess I'm just old-fashioned about oil changing.

I assume you're talking about Mobil 1 synthetic?

Re: Engine Oil/Additives for high mileage 3.0
 
So the choice is yours ... You can continue to do 3K oil and filter changes
and use regular oil dino oil, or you can use the 2.5-3X more expensive
synthetic and if you take Richard's advice, go 2.5X longer. Doing this also
saves you the cost of the filters as well, so on the surface appears to save
both time and money. But, keep in mind that you will need to add oil over
that period (at 142K miles, I'd guess at least another 3-4 quarts over that
7.5K miles) and your oil filter will collect 2.5X as much and could
constrict your flow of fresh oil. In addition, the detergents added to the
synthetic oil will break down and lose their effectiveness over that same
time period.

Again, it is your choice and I know many people who follow the
manufacturer's recommendation and change their oil at 7,500 miles and almost
all have gotten 100K from their cars before selling them. (The exception I
can recall came from a woman who did a lot of around town driving and not
highway miles.) I'm just not one of them since I feel the cost is minor
compared to the risk of waiting. I also only choose to use synthetic
(Mobile-1 10W-30) in one of my family's 5 vehicles due to the higher cost
and regular Castrol GTX or Valvoline 5W-30 (winter) and 10W-30 (summer)
depending on what is on sale at the time. For me, changing the oil myself
in my home garage is not a problem. In the 32+ years that I have been
driving, I can only think of one oil change that I had done by a service
center and that was because I was on vacation and 2,000 miles from home when
the 3K miles came up.

If you want to use conventional engine oil, there's nothing the matter
with plain Valvoline or Castrol or Pennzoil or Havoline. If you want to
use Synthetic, get Mobil-1; change the oil every 12,000 miles and the
filter every 6,000 miles.

"Synthetic blends" are largely a scam.

Not unreasonable with well-chosen oil and quality filters (not Fram).

Update your thinking!

> I assume you're talking about Mobil 1 synthetic?


That's the only kind of Mobil-1 there is.
