Topic: Oil analysis from my Dodge Dakota. Esso XD-3 0W-30

[ktm525]

2002 Dodge Dakota
4.7L AWD Quad
110 000 km total mileage
8000km on the oil (13 months) and one Wix filter.
Lots of short commuting trips with the odd high stress situation (towing) and dusty gravel backroads.

Esso XD-3 0W-30 synthetic. The Fe is a little high but I think OK. This oil still had plenty of life (TBN @ 5.9) after one year. I may go to 2 year changes next.

I use both the 0/30 and the 0/40

What is FE and TBN

How much does an oil change using Esso XD-3 0W-30 synthetic and a Wix filter cost you?

What is FE and TBN 

Fe is iron. A little high. Could be sourced from metal engine parts (bearings etc.) Still this number is reasonable for the conditions I put this engine through.

TBN is Total Base Number and is a measure of an oils alkalinity and a measurement of it's ability to nuetralize acids formed during combustion. The higher the TBN the more acid it can nuetralize.

XD-3 is a great group IV synthetic with a very robust additive pack (high zinc, high Ca). The original TBN is 12.5, after a year I have about 5 TBN left. The oil is still able to nuetralize acids.


For the other question:

I get XD-3 for $5/L. The Dakota takes 6L, so $30 for oil and $6 for the filter. $36/year for my oil change. Plus a little bit of my own time.

How much for the oil analysis?

[articsteve]

On May 2 of this year I paid $4.60 per litre. 4 litre jugs x 4 in a case for the 0/30.

I paid $5.30 for the 0/40 in the same format.  Price probably went up since then.

Same depot sells Mobil 1 for twice the price (Group 3).     Guy says ppl are married to the name even though it's an inferior oil.  That's brand power for ya.

Good work. My only concern regarding XD-3 is the 1.5% ash content. Potentially it could poison the catalytic converters?? I really don't know. I will switch my Volvo V70R off of it's diet of Castrol 0W-30 when the warranty expires and run XD-3.
