I just used 5qt QSED High Milage 10w-30 (w/ the 6th being QSUD 5w-30) purchased from Walmart last Christmas I believe in a Saab 9-7x 5.3 w/ AFM that consumes some oil. I just added a qt at about 50% on the OLM or around 3500 miles. From the standpoint quietness/smoothness/etc it seems no better...

Have a 2.Slo and have been using a 50/50 mix of Nextgen 5w-30/10w-40. Basically shooting for something close to the properties of a heavy 30 / light 40 similar to the Castrol GC the engine was probably designed to use. I wouldn't use this in the 1.8t as this is not a GC replacement by any means...

I just blended PP 0w-20 w/ Formula Shell 10w/40 1:1 for a heavy 30 11.3/66.2 in today's use-up-the-stash Silverado 5.3 oil change. Was going to go 60/40 or 2:1 for a lighter mix, but planning a doing a seafoam or kroil cleanup at the end of the OCI so I went a bit on the heavy side.

Very interesting, thanks. I never had given it a thought before reading this. Seems easy enough.

A great way to allow malwarebytes or others work better is a tiny program called RKill. It tries (and is usually successfull) in terminating most of the nasty program. Run Rkill then run you antimalware of choice. RKill does not remove anything, just stops viruses and allows your antimalware an...

without a doubt the motherboard audio has really improved over the last decade. Another factor though is the power of the cpus, the fact that most are dual/quad core processors, and along with gobs of available ram the onboard resources are leaps and bounds above the day and age when a separate...

Sounds to me like you have an SLI setup. From what I remember the 680i was a bit buggy anyway. What I would do is remove everything to a minimalist setup. 1 stick of ram, a low power (or pci slot video card) if you have one (if not back it doen to a single PCI-e card, no drives except the boot...

Also that's pretty thin stuff. 12 oz in 6 qts is about 6%. 12oz probably causes a 0.5-1.0 cST drop in Kv at normal ratios. Any cause for concern with that? Use a heavyier oil or offset w/ a qt of 20w50? Website says you do not replace the oil 1:1, just add zMax on top of the normal fill and you...

Has anyone ever come across results of ZMax usage eating the carbon and freeing up the rings in the 5.3l AFM engines?

I run purolator whites in a bunch of our cars. Changes occur between 5k and 7k without issue ever.

Have a 2006 Saab 9-7x that has 18" rims w/ 255/55/18 tires. Overall calculated height at around 29". I hate the options in this size as there are few and I've tried most of them, aka the softer compound tires wear quickly. They are the same platform as Chevy Trailblazers, Envoys, etc but...

I have been thinking about building the ramps out of 2x12s. The one thing these homemade jobs allow is the slower transition to height. Changing oil on low slung cars with air dams and regular ramps is a combination that does not mix if you care about the air dam. I wind up jacking the Jettas up...

sweet and imaginative shots.

Will one of the lubricating metals in the add pack, say moly or ZDDP, plate to any appreciable thickness or will it only build up a few atoms in thickness?

Seems like Valvoline gets bashed bt some folks for lower TBN but it doesn't look too out of line at all.

you did good

A question for the true gurus: Can an oil clean too well?? That engine appears to be spotless. I don't know the fine details of oil chemistry, but there should be a balance between the oil cleaning and the oil plating the engine with lubricating/sacrificial metals from the add pack. Is that...

Had an 85 Jetta Diesel NA. Pretty light on power. I think only around 45-50 hp, but once I learned to drive it, the 5 speed helped greatly. Consistently above 45mpg and I beat on it. Top speed I ever as able to get it was 95mph downhill. Uphill maybe 70ish. Changed oil every 2500-3000 w/...

if it were me, I'd mix either: 3 parts Maxlife 0w-20 to 1 part VR1 for a winter middle of the road 30 weight (10.5/63) or 2 parts Maxlife 0w-20 to 1 part VR1 for summer heavier 30 weight (11.3/69) both still maintain decent VI in the 150-160 range, slight boost to zinc levels (if that is...
