2020年12月23日 · I personally think the M1 EP HM is slightly better as a "high mileage" oil, in terms of it's seal conditioning and ability to slow seal leaks. Click to expand... The Mobil 1 HM 5-30 stopped my 01 Ford 150 with 160k from leaking out the front and rear main seals.

2019年6月9日 · that Valvoline High Mileage oil has extra seal conditioners (the main difference) but it also has a small amount of ashless anti-wear compounds, which I think is meaningless since all synthetic oils that pass dexos1 or VW 508 for example have good anti-wear performance already. She also says there are more dispersants to prevent deposits, but ...

2015年5月6日 · What are all of the Dexos1 High Mileage oils and which do you think is best? Valvoline Maxlife (both full synthetic and blend) and Castrol Edge High Mileage (full synthetic) are Dexos1 approved. Maxlife seems to be universally agreed to be a good product capable of stipping/reducing leaks. The...

2017年11月25日 · I read where the 0w oil eased the cold startup noises on other GM 5.3 owners trucks and also knew several people running a 40-viscosity oil in high mileage oil burning engine with success. Unfortunatly I couldn't find much in people that formerly used 5w30 now using a …

2019年8月14日 · The high mileage full synthetic version appears to be the best value giving you the most for the least money. I have the Walmart credit card, with 5% cash back on all online purchases (either delivery or store pickup). So the 5 quart jug of SuperTech High Mileage Full Synthetic 5W-30 oil is $19.98 * 95% = $18.98 / 5 quarts = $3.80 a quart + tax.

2018年8月2日 · My 2011 Honda CR-V has almost 111,000 miles. During the current OCI (normally 4K) I am in I have added over 1.5 qts. of oil in approx. 2,000 miles. I use Pennz. Platinum 5W20, the OM recommended weight is 0W20. I have no leaks and have no intention of doing an engine rebuild on a well running...

2017年2月18日 · I have a few quarts of Valvoline Max Life oil, for high mileage engines, that I have left over from a vehicle I traded. Would it be OK to used this oil in an almost new Kohler 7000 series engine in my lawn tractor? It is the correct viscosity.

2024年12月13日 · I have a 2003 Tahoe 5.3 with approx. 228k miles. It was dealer maintained, CarFax confirmed, up until 197k miles when I purchased it. I did change the valve cover gasket after purchase and the engine was very clean. I've used Valvoline high mileage early on and the previous two oil changes had switched to Pennzoil Platinum high mileage.

2020年11月22日 · It creates a bit of a cupped area where liquids can gather. It was full of pooled oil and clearly leaking onto the exhaust and burning. I could even see the oil sheen from the valve cover gasket downward. I don't like leaking oil, and the rear valve cover gasket is a bear to replace, so I went with a high mileage Pennzoil syn blend 5w-30.
