Delvac 1300 15w40 and Windstar

[jjbula]

Just got my analysis back from Schaeffers. The first analysis was Mobil 1 5w30 Oct-Nov. Interval 2,600 miles / 115,000 miles on vehicle. Mostly highway miles. Consumed 1 1/2 quart of oil and 3/4 quart of Castrol 5w30 added during interval. I ran chevron techron and, later, Berryman's B-12 chemtool to clean the fuel system. Maybe that contributed to high numbers.

Second analysis is Mobil Delvac 1300 15w40 Dec-Feb. Some highway, but more city driving than the previous sample. I thought the vehicle would stay in Alabama but there were 4 days it was in St. Louis in 15F weather. 2,900 miles / 122,000 miles total. Consumed no more than 1/2 quart. None added. 6oz. of Neutra added 100 miles before oil change. That appears to have thinned out the oil (12.44 cst).

You may have noticed another oil was between these two. I ran Schaeffer Blend 5w30 in between. Should have sampled but didn't get around to it.

Forgot to add that this had a coolant leak last summer and seems to be fixed since I added Prestone stop leak.

The first analysis showed a coolant leak and the second is after prestone stopleak. Blanks on the second set of numbers were blank on the form. I wish sodium and potassium had been measured.

second numbers are with a Bosch premium filter
and mixed city/highway driving

Schaeffer oil sample number:319085
Schaeffer's Labs comments:
Contamination and additive depletion levels normal. Maintain current oil drain interval.

I am disappointed with the overall wear and sulfur. I used techron and later B-12 chemtool after a suspected bout with bad gas. Hesitation and poor idle were the symptoms. Since then I have only bought gas at Shell, Chevron, Exxon, Conoco or Amoco stations. No more problems.

Also, after I thought the coolant leak was plugged, I waited another 800 miles and changed the oil. After draining the pre-coolant fix oil I filled with supertech oil for a 1 minute idle and drained again, then the new filter and mobil 1 were put on/in.

Something I thought was odd was how thin the mobil 1 was during this interval. I've used mobil 1 often and this is the thinnest I've seen it. When I pulled the dipstick out oil instantly started to drip off the end.

Looksd like you should go back to the GTX

. Can't help wonder that the Mobil 1 did bad due to residual from radiator leak. Actually that's probably about right for the viscosity of the Mobil 1. Its especially disappointing because its the SuperSyn. I'm starting to believe the 0W and 5W Mobil 1 is a waste.

 

[jjbula]

I have come to believe that M1 may be good for some engines and not others. Engine design and age may be the biggest factors.

I think I may test a 5w40 or 10w40 next, during the summer, to see how it compares to the GTX.

I don't know why the GTX did so well. It was the first oil used after Auto-Rx treatment and had residual Auto-Rx to help out. A small amount of coolant may have helped keep the GTX thicker.

Maybe I should try a "high mileage" 10w30 that is formulated slightly thicker.

In what sense Al?

 

[buster]

For older engines it is a BIG waste. I went through Mobil 1 0w30 in a month. This viscosities are only good for new, tightly built engines. If you don't have one, your throwing $$ down the drain.

 

[Bror Jace]

I've always thought that Castrol GTX was a little low on detergents and/or dispersants ... which is why it looks so clean even after being in an engine for a long time.

Could it be possible that the Mobil 1 is cleaning up past residue Castrol GTX failed to take with it?

It just seems that the 5W and 0W oils just don't seem to do that well. Or at lest not as well as the 10W. Maybe it's just the Margarita that I just drank

I agree. I'm running the 10w now. Delvac 1 is next. I take back what I said before about wanting to change my oil no more then 7,500 miles. I'm getting sooo tired of changing it with the driving I do. I can't take it anymore. I can't think straight sometimes (as some can already tell

) By May though, I'll be knocking 2.5k off my driving per month. After that it's back to Amsoil and I'm going all out.....to 15k miles!!! Just to give you an idea, I live in south Jersey (10 mins outside philly) work in Princeton, NJ and visit my student wife at Cornell in Ithaca NY (4hrs.) every other weekend. I'm a fool.

jjbula,

You ran a longer change interval with the 15w40 and yet all the wear rates are significantly lower, so I'm not sure why you are complaining? The 15w40 will work even better in the warmer weather coming up.

Forget about the sulphur reading - run a TBN test the next time around if you want to see how the oil is holding up. The sulphur reading is simply a reflection of fuel quality, not oil performance.

This is interesting because the additive packages on the commercial, heavy duty oils ie. delo, rotella ,mobil 1300 all have very high additive levels. Compare them with Amsoil ,Redline and Schaeffers and there is that in common and that is why those oils are better in general the higher additives.I guess the additives make the oil then the base stock gives it life ??? what do you guys think?

That is the million dollar question. My older windstar engine has some age issues and may be in need of thicker oil and high AW additives. The downside is more heat being generated and lower gas mileage.

The used oil analysis on my Camry are just the opposite. The 10w30 non-moly oil and 5w30 Schaeffer blend did very well. I don't think I need to use 15w40 in that engine. The temptation is there, though, since the $5.77/gallon price on Pennzoil Long-Life 15w40.

The pour point is even better than the Pennzoil high mileage 10w30!
