AMSOIL XL 5w30 (XLF)
Kinematic Viscosity @ 40°C, 50.9 cSt
Is this the thinnest(@40°C) Xw-30 on the market?I know it's a GRPIII base,that's not the question.I'm thinking this might be a good Xw-30 to use in a vehicle spec'd for a 5w-20.

I've been looking at their XLF line (I used to bash the price). If you look at the XLF- GF-4 line and what has happend to Mobil 1 GF-4, I think they look more appealing now. I'm becomming more interested in using a well formulated Grp III oil with a stronger additive package. The specs of the XL line are on par with M1 GF-4. The 5w-20 is a decent oil also.

If you are interested in this oil and are close to a Mills Fleet Farm they have it on sale this week for 4.49qt. Just a heads up.

QUAKER STATE WINTER SYNTHETIC BLEND MOTOR OIL beats the XLF by a nose @ 49.9 cSt.Any other 30 weights with a similar vis @40°C?

The Amsoil, XL/5w30 has a VI of 196 as I recall? The only concern I'd have about a Group III basestock with a VI that high is that it would shear in service. I have no data to support this, it's simply based on my knowledge of how oils are formulated.

TBN of the XL line is listed as 10.2, or about the same as the new GF-4 rated, Mobil 1.

I had to put a new engine (cracked block) in my 1992 Chevy plow truck. It was a new GM crate engine and I had them put in the XL7500 5w30 and its been in there for just over 5,000 miles now, from 0 miles on engine. I am going to change it in April (6 months and likely 6000 miles. I may do a used oil analysis to see how it looks.

I have not had to add 1 drop of makeup oil, just checked it yeaterday and it looks like its only been in there for 100 miles. Clean looking and I only have an AC Delco filter on there, PF52. I have also used the XL in my 1993 Lumina since the oil came out.

Especially when the Mobil 1 7500 product is a group II/III blend (as stated on the bottle) plus the fact that the full syn. stuff is closer in price to Amsoil.

Good for me.

BTW, I sell a ton of the XL line and I think it works great for the money. If a customer wants great protection, and does not want to extend drains out until the next century then the XL is the way to go.

Hope this helps.

Oh and it's API certified, with the nice little Doghnut and "energy conserving" label. Can't mess with that.

I am so confused now. I thought the XL 5w30 was not a true synthetic and that the ASL 5w30 is the better choice?

 

[Mike_dup1]

Its synthetic but not 100% synthetic. The ASL is better oil but if you are going to change it out often, then the XL is another choice. Many go for this when they fear longer drain intervals.

I used in my my 1992 truck because it only gets used primalry in the winter and often only about 5-10,000 miles at most and I had the oil from what I use on the older Lumina which only goes about 3-4000 miles a year as a grocery getter and to chaffaur my 85 yo mother to chuch, Dr etc.

But if you want the best, ASL and ATM are very good choices. They had formulated these oils to pass API certification whereas the ASL, ATM etc have additives that won't pass API. In other words they had to downgrade to meet API.

I use the ATM (10W-30) in my 2002 Firebird. They are Amsoil top selling oils.

Castrol's web-site isn't giving this # now.

Syntec 5w30 anyone.
