LF4 Engine Oil Temperatures and Type

[raptor5244]

Some oil pressure specs I ran across in service information. I'm assuming these are likely minimum values fully warmed up as the first listing (for the 2.0L not shown here) said 100 ° C.

3.6L: @ Idle - 69 kPa (10 psi)
3.6L: @ 2, 000 RPM - 138 kPa (20 psi)
3.6L: Piston Cooling Jet Valve OpeningPressure - 2.2-3.0 bar (32.3-44 psi)

Interesting, I have never seen anything close 10psi at idle. Maybe dips to 17psi when over 200 degrees. Since I change the oil yesterday it is up 2-3psi at idle (20 psi at 196 degree oil temp) so I assume the oil thins out over time. I never had a digital gauge with this precision so I never paid much attention to the analog gauges in the past.

For those using Mobil 1 5w-30, for just a few more pennies you can get Mobil 1 Extended Performance which uses a better base and is generally regarded a better oil for the turbo bearings. It comes in 5qt jugs, so I buy three at a time which gives me two oil changes (4bw = 7qt) and I have one qt left for top off. I find mine will consume about a qt of oil over 7500 miles. I have been using the UPF63R filter. Note, the filter flute wrench is not the same for the UPF63R as the PF63.

Last oil change, I must have cranked on the filter a bit tight, took both the flute wrench and the adjustable band wrench on the body together to get the filter off.

What size/flute wrench do you use for the upf63r?

I think it is 74mm 14 flute. The factory filter is 15 flute. I just use one of these if needed to take it off. Hand tight only when installing the new one.

It looks like the Mobil 1 Extended Performance is thinner than the regular Mobil 1 (10.15 vs 10.8). Have you tried both? I feel like a thicker oil would be better.

I don't see it mentioned in this thread but when I was poking around, by far the cheapest place to get Mobil 1 Supercar 0W-40 is rockauto.com ($7.47/qt). I believe it's also a good place to pick up UPF64R filters.

They also carry a lot of GM/Delco part numbers and are worth checking when shopping.

If you already have an Amazon prime or other similar subscription, the free shipping can tip the scales away from Rock Auto.

I do check amazon which sometimes is cheaper for Delco parts but for Mobil 1 supercar, amazon is way more than rockauto.

Good lookin out my dude. Wouldn’t have found that one. Thanks

The manual says to check the oil at every fill up. Has anyone experienced burning through oil fast enough that this was necessary in the first 1500? I plan to get oil changed at 500, then again at 1500, and go standard from then on. Should I be carrying around a quart or two just to be safe in the meantime? I’ve got 44 miles on it at the moment.

This is for the LF4, so might not help you. I checked my oil level at 400 and 800. It was right at full both times. I got it changed around 870 miles.
