    PQIA Noack test temp

    I've noticed that recent Noack tests from PQIA have been @ 245.2c instead of the ASTM D5800 standard 250c https://pqia.org/pennzoil-platinum-sae-0w-20-full-synthetic-motor-oil/ vs http://www.pqiadata.org/Pennzoil_Platinum_0W20_dexos.html Anyone know why this is and if the results could be...

    New cold pour test video of 5w30 Syn

    Haven't seen this video before and it's one of the fairest tests done IMO because of the funnel used as a restrictor. Seems like PP/PUP is the king of 5w30 in the cold which is surprising since M1 always had the best reputation for cold performance due to its PAO content. Also surprising is...

    ACDelco 0w20 full synthetic dexos1 gen2: opinions?

    Bought from a local seller for a good price, wondering if anyone has seen a VOA or UOA for this? It's made by Mobil for sure because of the bottle design. The only ACDelco 0w20 VOA I've seen is for an older Dexos1 gen1 formula here: http://pqiadata.org/ACDelco_0W20.html

    Which high mileage oil has the most seal swelling?

    1MZ-FE Camry just started to leak oil from the valve cover which is a common issue. Willing to give HM oil a chance, which brand has the most seal swelling additives? I'm partial to M1 but will buy whatever has the highest chance of stopping the leak. Thanks for your inputs!

    Best civic brake pads from RA?

    Need new front pads for GF's 09 Civic DX sedan, the factory pair only lasted about 45k KM (28K miles) and the replacement set were wagner thermoquiets that had a similar longevity. Hoping to find something that can last for at least 60K KM. I've heard great things about Akebono but AFAIK, their...

    Fram High performance racing oil filter?

    http://www.fram.com/media/64582/fram-racing-filter-sell-sheet.pdf Did anyone use or tear one of these apart before? 94% efficiency seems lower than 99% claimed by Fram Ultra though.

    Parked car with deflated tires, sidewall damage?

    Family friend let her Camry sit in the garage for 2 years straight. 2 of the tires got deflated probably due to a slow leak from the valve stem or bad contact with the rim. Are the sidewalls permanently damaged now? I know there will be major flat spotting that may be permanent, but if that...

    M1 is the smoothest

    I maintain 3 vehicles: 09 Civic R18, 05 Matrix 1ZZ-FE & 05 Lexus ES330 3MZ-FE The Matrix was acquired about 2yrs ago /w ~135K KM and I got the fluids changed after the first week. Pretty sure it's been on bulk dino its whole life so it was idling rough. I put in M1 5w20 to start cleaning it out...

    How does fuel dilution affect HTHS viscosity?

    Direct injection + Low tension piston rings in modern engine design is causing fuel dilution to go through the roof. Yes, many blackstone UOA reports seem to indicate a relatively safe 1-2% fuel dilution but looking at the low KV100 & Flashpoint numbers, actual readings are probably closer to 5%...

    Idemitsu 0w20 or PP/M1 5w20?

    6-7K mile interval for a 2015 Corolla with below zero winters & stop/go traffic, which do you think is better? The Idemitsu oil is from Subaru or Honda (yes Honda in Canada still uses Idemitsu for 0w20 whereas Honda USA uses CoP), both SN rated (no high moly) I know the 0w20 will be better for...

    Using ATF to clean out sludged engine?

    Everywhere on the internet, whenever someone posts valve cover pics of a sludged engine, people start suggesting the use of ATF in the engine to clean it out because it is loaded with detergents. This myth has been perpetuated for decades it seems, but has anyone actually verified the claim...

    Valvoline Maxlife 0w20 Synth blend?

    Did anyone try this oil before? Specs here: http://content.valvoline.com/pdf/maxlife.pdf Does anyone know what percentage of the basestock is synthetic? Would the seal conditioners damage anything in new engines? Any experience/input would be appreciated. Planning on using it in a 2015 Corolla...

    Does cold weather cause oil consumption?

    09 Civic R18 engine with around 41K miles on it. Never noticed any oil consumption before, but today I checked and the dipstick was half way down. Only 2500 miles since last oil change (Dec 2014) with Subaru 0w20 (Idemitsu made) and it took about 1/4 quart to bring it back to full. We did have...

    New synthetic motor oil cold pour test

    Looks like Mobil1 is still king, surprised by how slow the Castrol Edge was. AFAIK, the lightest grade for Rotella T6 is 5w40 which is doing better than Castrol Edge 5w30. Who is the OEM for Walmart Synth in USA? Previous test by the same person here:

    05 Toyota Matrix under valve cover pics

    1zz-fe engine /w 136k KM (84.5k miles) on it, unknown previous maintenance record. I'm guessing its had quick lube bulk dino for every 5-8k miles, no maintenance minder light in Canadian models AFAIK. Running on its first change of M1 5w20 now. I honestly expected a lot more varnish than this...

    Follow your oil life meter

    I'm in charge of servicing a 09 Civic with the R18 engine. The OLM seems to be really good at compensating for varying driving conditions. Oil was last changed in early Dec 2014 then the cold cold winter hit with morning temps regularly at -10 to -20C. Daily commute is about 7KM each way which...

    Bosch 3422 (PL20195) & Mopar 0FE00308 cut open

    I've stayed pretty neutral about the whole tearolator hate train because I think while tears are bad, it's not significant enough to cause much of a bypass because the tears only account for maybe 0.01% of the total surface area on the filter media. Anyways, the Bosch 3422 was used on a Lexus...

    New Denso TT Iridium spark plugs

    http://densott.com/ New spark plug design with Iridium tip + fine wire platinum ground electrode. AFAIK, NGK doesn't produce this design yet for mass market use, but they do mention it as the next evolution of spark plug design here: http://www.ngksparkplugs.com/pdf/dyk_evolution_plugs.pdf...

    My friend's car has been overfilled for 150k+ KM

    I'm laughing my as.s off here. He bought a used 01 Accord for dirt cheap about 2 months ago. It has a new engine put in about 150K KM ago, it currently has over 300K KM on the body. He did the first oil change a few weeks ago, 5L jug of Motomaster 5w30 dino on sale @ CT. Used an oil extractor...
