Unusual oil question
I was changing oil on my MY 83 Saturday. I went to Advance Auto and bought two of the one gallon Jugs of Castrol 20/50 like I use in all my cars. One of the jugs was the newer/spiffier design while the other was the regular shape. While adding the oil to the car I noticed the oil from the new jug was pretty slow to flow and was very light in color. The other was just like I am used to in color (darker) and it flowed faster out of the jug. Have they changed it that much? I know about the new standars and am looking into using somethingelse. (save me the Amsoil testamonials).

I've used Mobil One Synth for many years and when they moved to the new design on their bottles, they also put out info that they had updated their wear lubricants. Old type looks thicker and darler, new type looks thinner and lighter colour. I know for gear oil, the old stuff I drained out was much better than the new stuff I put in.

Read the certifications on the bottle. The old one is probably SL rated and the new one SL/SM rated. SM has the new wear and low metals requirements that are worrying people.

Hi,
chrly924s - Rotella T Multigrade 15w-40 is an excellent product to use in your car (in a ambient range of 10f to 100f+)
As "heinrich" has mentioned, M1 15w-50 (any version) works well in a 928 too - including the lastest formulations. This appears to be the most popular 928 engine lubricant used in NA
Lubricants that have the ILSAC "GF-4" on the container should NOT be used in a 928
It is unwise to add any supplementary additive to a modern engine lubricant
Regards
Doug

chrly, go to google and type in ZDDP , then have a look at the 2nd one down from the top ( interpretation of experiments of ZDDP ) and then the third one down from the top ( ZDDP in older engines ), it explains quite a lot . Regards . BB .

Hi,
JET951 - As usual you are dealing in an area where with all due respect you know very little. The latest range of NON ILSAC GF-4 rated lubricants (both PCMO and HDEO versions) are showing better anti-wear characteristics than earlier versions!
And, whilst you may print what you will on "Landshark", readers on here will know that I have always recommended HDEO "mixed fleet" lubricants such as Rotella T. Of these, the very best are the 5w-40 synthetic versions but not all persons wish to use a synthetic lubricant!
As well, I have used them for over 50 years, and in Porsche engines since 1968!!!
Read more on Landshark and you will see I recommended these lubricants on there right from the start - and I still do!!
These were the original Factory fill lubricants in Porsche engines since the 1950s
The lubricants I recommended in the previous Post on here have the highest levels of anti-wear additives - including (but not exclusively) ZDDP which is to all intents and purposes a dying ingredient! The new additives are much better performers!
Deal with what you know not what you hear!
Regards
Doug
